The subshell electronic configuration is the arrangement of electrons in subshells (or orbitals) of an atom. It is usually expressed as a series of numbers denoting the number of electrons in each subshell (or orbital). The subshells (or orbitals) are grouped into four primary blocks: s, p, d, and f. The s block contains the …
The electronic configuration of chromium (Cr) is [Ar]3d54s1 and that of copper (Cu) is [Ar]3d104s1. Both chromium and copper have incomplete d-orbitals, but chromium has more electrons in its d-orbitals than copper. This is because chromium has two extra electrons in its d-orbital, while copper has one extra electron in its d-orbital. This peculiarity gives …
Noble gas electronic configuration refers to the complete electron configuration of the outermost shell of a noble gas, which is a group of elements in the periodic table that are highly stable due to having full valence shells. The noble gas electronic configuration for the first six noble gases is as follows: Helium (He): 1s2 …
When filling electrons in a subshell, electrons are filled in order of increasing energy, beginning with the lowest energy level. The subshells are filled in the order of 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p.
An energy crisis is a situation in which the demand for energy exceeds the supply. It can refer to shortages of oil and other fossil fuels, electricity, or other forms of energy. Energy crises can have a major impact on the economy and social well-being of a nation. Common causes of energy crises include conflict …
Green energy is energy that is generated from renewable sources, such as solar, wind, hydro, and geothermal power, as well as from more efficient use of natural resources, such as energy efficiency and conservation. Green energy does not contribute to climate change and is considered to be a clean and sustainable energy source.
Nuclear pollution is the release of nuclear materials into the environment that can cause harm to living organisms. It is caused by activities such as nuclear power plant accidents, nuclear weapons testing, radioactive waste disposal, and the mining and processing of uranium and other radioactive substances. Nuclear pollution can lead to serious health effects such …

Nuclear fission is a nuclear reaction in which the nucleus of an atom splits into two or more smaller nuclei, releasing a large amount of energy. This reaction is the basis of nuclear power generation and nuclear weapons, and is responsible for the vast majority of energy released from uranium and plutonium.
Nuclear energy is the energy released from the nucleus of an atom. It is created when the nucleus of an atom splits (nuclear fission) or is combined (nuclear fusion). Nuclear energy can be used to generate electricity, propel ships, and to create medical and industrial isotopes. Nuclear energy can also be used in the form …
.Geothermal energy is an alternative energy source that harnesses heat from the Earth’s core to generate electricity, hot water, and other uses. Geothermal energy is renewable, clean, and abundant, and it can be used to generate electricity, heat buildings and homes, and provide hot water for a variety of uses. It is also a cost-effective …
