The electron structure of a chemical element Indicate the location of electrons on shells.
one valence electron
The electron-pair geometry of CS2 is linear because the Lewis structure is S=C=S. Double bonds act as one electron pair to help determine electron-pair geometries of molecules according to VESPR theory
Carbon owns 6e- and 6p+ so the electronic structure is K2 L4 .

The electron configuration of the chloride ion is: [Ne] 1s2.2s2.2p6.3s2.3p6.
Electronic configuration: - Chlorine: [Ne]3s23p5 - Fluorine: 1s22s22p5
An outer electron shell with only one electron.
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).
The number of electrons needed to be lost/gained to gain a stable electronic structure. For example, Sodium needs to lose just 1 electron to make its electronic structure stable, so the ion it forms is Na+ .
