The Z atom has electronic configuration (image), what type of ion will form the Z atom?
a) Z^+
b) Z^2+
c) Z^3t
d) Z^5-
Solution
1) Since one atom contributes a pair of electrons and shares equally so the type of bond is
covalent coordinate(by definition) .
Therefore option (d) is correct
(2) The electronic configuration of Z is 1s 2
2s 2
2p 6
3s 2
3p 1
The nearest noble gas electronic configuration is 1s 2
2s 2
2p 6
and is for Neon . So the element Z
can looses two 3s electrons & one 3p electron totally 2+1 = 3 electrons from Z to from Z 3+
Therefore option (c) is correct
