(v)
b) () Draw the atomic orbit structure of formation of:
2210 (1Electrovalent compound - sodium chloride (Na = 11, C1 = 17)
(2) Covalent molecule - nitrogen (N = 7]
Name - a covalent molecule formed from two different elements, h
three single covalent bonds.
(iii) Differentiate between -
(1) Shared pair and lone pair of electrons with reference to -
covalent molecule - water (H =1, 0 =8]
(2) Duplet rule & octet rule​

Answer 1

Answer:

Sorry but this is not understood

Answer 2

Answer:●components of compound retain their properties

●in H2O molecule.....oxygen carries 6 valence es-.....it shares 2 of its es- with 2 hydrogen atoms to make bond and form water....now we will call these shares es- as shared pair.....and the other 4 es- remaining with oxygen are called 2 line pairs

● a covalent compound formed by two different element atoms= HCl

●when taken in Kelvin, the zero of absolute scale resembles -273°C,

Explanation:I can't understand the rest of questions asked by you......hope it will help you somehow:)
