Question

Octet rule states that elements tend to combine by losing, gaining or sharing electrons such that each atom has eight electrons in its valence shell. Why only 8 electrons?

• A. Because 8 is a fancy number
• B. Because noble gases have 8 electrons in their valence shell
• C. Because elements with less than 8 valence electrons are less stable
• D. Both B and C

Answer 1

The correct option is D Both B and C

Since all noble gases have 8 electrons in their valence shell and they are highly stable than those elements with less valence electrons. The octet rule sticks with 8 electrons. Noble gases are observed to be inert and not reacting with other elements.
