Question

Elements of the oxygen family need only-----------electrons to complete their octet. *

a) 1

b) 2

c) 3

d) 4

​

Answer 1

Answer:

2 electron to complete octate

Answer 2

Elements of the oxygen family need only 2 electrons to complete their octet.

• The electronic configuration of oxygen is 1s²2s²2p⁴. Therefore oxygen has just 4 electrons in the p orbital that means it has 6 electrons in the valence shell.
• According to the octet rule, the element becomes stable by completely filling its outermost valence shell.
• For oxygen to completely fill its valence shell it would need 2 more electrons.
• The oxygen family would have the same electronic configuration of the valence shell as that of oxygen, therefore they all would need 2 electrons to complete their octet.
