Elements-W,X,Y,Z have electronic configuration
W=2,8,1
X=2,8,7
Y=2,5
Z=1
i) What type of bond is between a)W&X b)Y&Z
ii)What is the formula of the compound formed between a)X&Z b)W&X
1. W=2,8,1=11 i.e Na and X=2,8,7 = 17 i.e Cl
Therefore, the name of compound is Sodium chloride , which forms ionic bond by an attraction between the +1 sodium cation and the -1 chlorine anion.
Y=2,5 =7 i.e N
Z=1 = H
Therefore , the name of compound is NH2 . Nitrogen has 5 valence electrons , 1 electron is shared with each hydrogen to form a covalent bond.
2 . X=2,8,7 = Cl , Z=1 =H , Hence, the formula of compound is HCl.
W=2,8,1 =Na , X=2,8,7 = Cl , Hence, the formula of compound is NaCl.
