i know s=2 p=6
what d=??
what d=??
The number of electrons that can fit on each energy level is determined by the formula 2n^2, where n is the energy level number. For example, the first energy level (n=1) can hold a maximum of 2 electrons, the second energy level (n=2) can hold a maximum of 8 electrons, and so on.
The maximum number of electrons on the outermost energy level, also known as the valence level, is 8. This is the case for all elements with the exception of hydrogen and helium, which can only hold a maximum of 2 valence electrons.
The number of electrons on each energy level determines an atom's chemical properties. The outermost energy level, which contains the valence electrons, is the most important in determining an atom's reactivity and ability to bond with other atoms. Atoms with a full outermost energy level are stable and less likely to form bonds, while atoms with unfilled outer energy levels are more reactive and likely to form bonds with other atoms in order to achieve a full outermost energy level.
Yes, the number of electrons on each energy level can change. Atoms can gain or lose electrons through chemical reactions, creating ions with a different number of electrons than their neutral state. Additionally, electrons can be excited to higher energy levels through the absorption of energy, and then return to a lower energy level by releasing that energy in the form of light.
The number of electrons on each energy level is directly related to an element's position on the periodic table. Elements in the same group have the same number of valence electrons, which contributes to similar chemical properties. Additionally, as you move from left to right across the periodic table, the number of valence electrons increases by one for each element, until reaching a full outermost energy level at the far right side of the table.
