Use molecular orbital theory to determine the ground state electron configuration of f2 and f2+

Atomic number of F = 9

Electron configuration of F:-

⁹F = 1s² 2s² 2p⁵

Incase of F2: Total electrons: 9 + 9 = 18

For F2 the ground state electron configuration would be:

F2 = (1σ)²(1σ*)²(2σ)²(2σ*)²(2pσ)²(2pπ)⁴(2pπ*)⁴

Incase of F2+: There is loss of one electron from neutral F2. Total electrons: 18-1 = 17

For F2+ the ground state electron configuration would be:

F2 = (1σ)²(1σ*)²(2σ)²(2σ*)²(2pσ)²(2pπ)⁴(2pπ*)³

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
