Question

10. Combining capacity of Ar and Na respectively are
a) 4,3
b) 0,1
c) 1,0
d) 3, 4​

Answer 1

Answer:

ok

Explanation:

options d is correct answer

Answer 2

Combining the capacity of Ar and Na are respectively 0,1.

• Ar is an inert gas. The electronic configuration of Ar is as follows-
• ${1s}^{2} {2s}^{2} {2p}^{6} {3s}^{2} {3p}^{6}$
• Hence it contains a filled 3p orbital and is highly stable so, it remains inert and its combining capacity is 0.
• Na is an alkali metal. The electronic configuration of the Na atom is as follows-
• ${1s}^{2} {2s}^{2} {2p}^{6} {3s}^{1}$
• Hence it required one electron more to get stability. So, the combining capacity of the Na atom is 1.
• Hence the correct option is b.
