Quick 'n easy question (electron configuration)
Electron configuration of P2+ (phosphorus 2+)? w/ half-filled p orbital I would do: [Ne]3p3 without half-filled p orbital I would do: [Ne]3s2 3p1 I usually go w/ the half-filled orbital answer since that's more stable...so why is it the latter? (Source: Student Doctor Network)
