Electron Configuration Chart

The electron configuration  of an atom of any element is the of electrons per  sublevel of the energy levels of an atom in its ground state.  This handy chart compiles the electron configurations of the elements up through number 104. How to Determine Electron Configuration To arrive at the electron configurations of atoms, you must know the order in which the different sublevels are filled. Electrons enter available sublevels in order of their increasing energy. A sublevel is filled or half-filled before the next sublevel is entered. For example, the  s  sublevel can only hold two electrons, so the 1s  is filled at helium (1s2). The  p  sublevel can hold six electrons, the  d  sublevel can hold 10 electrons, and the  f  sublevel can hold 14 electrons. The common shorthand notation is to refer to the noble gas core, rather than write out the entire configuration. For example, the configuration of magnesium could be written [Ne]3s2, rather than writing out 1s22s22p63s2.

Influence Of Organizational Behavior On Accounting...

Article #2 Abstract. The article reviewed was The Influence of Roles and Organizational Fit on Accounting Professionals’ Perceptions of their Firms’ Ethical Environment. The key of the abstract is to emphasize the influence of organizational behavior on accounting professionals and their ethical behavior (p. 125). Introduction. The authors study reasons of potential discrepancies between leaders and non-leaders of accounting firms. The firm’s ethical norms directly influence the behavior of its members. The researchers state that it is important to identify and understand the factors that affect ethical norms in the organization (p. 125). The firm’s leaders should play a meaningful role in building and supporting the ethical environment. The main objective of research is to analyze motives of perceptions’ inconsistencies in of the ethical setting between the management, partners, and other accounting professionals of the firm. The study is important through its investigations of influential factors of ethical standards on perceptions of accounting firm’s members, and in reducing the gap between partners and non-leaders of the CPA firm. The authors consider two problems of the study: greater ownership interest promotes the decision leadership in the company, and lack of non-leaders participation in modeling the firm ethical environment (p. 126).

Adolf Hitler As Modern History s Ultimate Monster

When referring to Adolf Hitler, one’s mind undoubtedly ventures to his leadership of the Nazi Party during World War II and his execution of the Holocaust against Europe’s Jewish population. He is, without doubt, one of the most powerful and evil leaders of the twentieth century. Through investigating his background, his rise to power, the details of his political party, and the events for which he was responsible, one is able to conclude that Adolf Hitler can be viewed as modern history’s ultimate monster. A crucial element to fully understanding Adolf Hitler is to understand his early life through examining his family, education, and aspirations. Adolf Hitler was born on April 20, 1889, which happened to be Easter Sunday. He was born in Braunau, a small town in Austria along the Inn River, a border that divided the Austro-Hungarian Empire and the German Empire. As a child, Hitler faced a turbulent home life, much of which can be contributed to the behaviors of his father. Alois Hitler, Adolf’s father, was a womanizer who had a long history of sexual relations and illegitimate children. Born illegitimately himself, by the time Alois met Karla Pà ¶lzl, the mother of Adolf Hitler, he already had three illegitimate children and several sexual partners, including two wives. Alois Hitler was not only a womanizer, but he was also incredibly violent. Adolf’s older brother, Alois Jr., fled his household when he was fourteen as a result of the violence of his father.

Future Generation Computer Systems †Free Samples to Students

Question: Discuss about the Future Generation Computer Systems. Answer: Introduction: The researchers evaluated the kind of security risks for computers and the factors that determine the probability that the computer security could be compromised; the authors aimed at understanding the factors that determine the probability that a computer node within the network is compromised (1). The authors, being professionals in various institutions of higher learning and research, undertake a a primary research approach using a case study to identify and validate different types of threats in a typical university IT network (2). The researchers established that the probability a computer node within a network is comprised is largely dependent on the set of reachable services that are running on the host (computer). The authors found that several attacks take advantage of specific network services vulnerabilities to bypass authentication requirements and gain access to the system. Further, it was established that some malware can scan for services autonomously to identify possi ble targets or open ports actively after infecting a network. (3). The proposed novel approach to identify and then quantify individual computers susceptibility to cyber threats with respect to the network services being run on these computers can help organizations map their threats and manage risks (4). The main drawback of the research is that by being a case study, it cannot be easily replicated and so the findings may not be universally applicable (5) The research reviews and classifies the security threats for information systems, premised on the fact that as more organizations use data and information in information systems, there are significant threats to these systems (1). The authors are eminent professionals in their various ICT fields, including software engineering, network engineering, and security and are senior members of faculty in various institutions of higher learning (2). Using analytical methods; the authors sought to develop a new model of classifying identified security threats broadly into internal and external threats. The classification is based on the threat sources and their impacts (3). The authors develop a new model that classifies most information security system threats as either internal or external, which can be human, environmental, and technological threats. The threats can either be malicious or non-malicious (4). The drawback is that it reviews existing literature, despite developing a new model and does not provide effective solutions (5) In this paper, the authors take cognizance of the increased use of cloud computing; being a relatively new technology, it has some inherent risks that the authors investigate (1). The authors are professionals that are highly regarded in their various ICT fields, and are senior lecturers of higher education institutions (2). Using a descriptive analysis based on information systems and software engineering design, the paper identifies and evaluates some of the security threats in cloud computing environments and proposes solutions (3). The paper proposes the use of a trusted third party to assure security within the cloud environment, employing a public key infrastructure, as well as LDAP (Lightweight Directory Access Protocol) and SSO (SINGLE Sign On) (4). The limitations of the study is that it is analytical and descriptive, and does not use primary or experimental methods to evaluate cloud security risks before developing solutions The use of mobile devices and networks is increasing, especially with the envisaged introduction of 5G networks, however there will be increased network security threats (1). The authors are well regarded and highly published and referenced professionals in their respective ICT fields, as well as contributors to ICT research and training (2). Using a comprehensive literature and research survey or recent works, the authors evaluate mobile SDN networks and their network security threats (3). The authors establish promising aspects that will ensure networks are better secured, using SDN in mobile networks, such as network hardening. Various SDN architectures are discussed (4). The research is exhaustive, but reviews past research rather than undertaking new progressive (primary) research The research focuses on the cloud and its security challenges and their solutions, considering the increased trend of more people using cloud platforms for computing (1). The authors are well regarded professionals with great expertise and understanding of their fields, including cloud security; they are also extensively published (2). Using an in depth literature survey, the authors evaluate some of the challenges of cloud platforms security (3). The authors establish that migrating ICT resources to third parties create and multiply security threats such as data loss and unauthorized access with proposed solutions being stronger authentication management, multiple cloud backups, and strong access APIs (4). The research limitation is in using surveys is that the authors are mainly re-writing research that has been done and not undertaking any new ground-breaking research.
