how does the complete filling of a subshell affect e? no apparent effect produces chemical stability; therefore decreases e produces chemical stability; therefore increases e e becomes very high because the atom becomes inert

Phosphorous can form an ion called phosphide, which has the formula p3−. this ion can form an ion called phosphide, which has the formula p3−. this ion properties very similar to those of pforms when a phosphorus atom loses three protonsis called a cationcontains 18 electrons
