Calcium has an Atomic Number Z = 20, so its electron configuration is:
K:2, L:8, M:8, N:2
So Ca has two outer-ring electrons.

each and all of the atoms you indexed have the two greater or decrease than various electrons equivalent to the style of the protons (a condition mandatory to make the atom impartial) different than Cu (ignoring the little - examine in front of all yet Zn). So all yet Cu have 8 electrons of their outer ring. with the intention to easily, an entire compliment is 8 electrons interior the outer shell. Ag, Ca, and Zn have lost electrons to end this, Cu is impartial yet will ought to lose an electron or 2. they'll now ought to neutralize with a adverse ion-subsequently the compound kinds.
