Question

If valence electrons of an atom are 2, then:

• A. It has to shed 2 electrons to achieve stability.
• B. It has to gain 6 more electrons to achieve stability.
• C. The outer most shell has 2 electrons.
• D. All of these.

Answer 1

The correct option is D

All of these.

If valence electrons of an atom are 2, it means that the outermost shell has 2 electrons.If outermost shell has 2 electrons, it can get rid of 2 electrons or get 6 electrons to become an octet.
