Electronic Structure
Sulfur
A benzenoid is a compound with an electronic structure analogous to that of benzene.
Carbon owns 6e- and 6p+ so the electronic structure is K2 L4 .
Group 1 elements have one electron in their outermost energy level, giving them an electronic configuration of ns1, where n represents the energy level. For example, lithium has an electronic structure of 1s2 2s1, sodium has an electronic structure of 1s2 2s2 2p6 3s1, and potassium has an electronic structure of 1s2 2s2 2p6 3s2 3p6 4s1.
The element whose electronic structure is [Rn]7s2 = Raradium
The chemical properties of any given element are the result of it electronic structure. The mass number is not related to the electronic structure because the mass includes neutrons, which not related to the electron structure (unlike protons). Any given element exists in more than one form (called isotopes) which have different numbers of neutrons, but the same electronic structure (and the same number of protons).
