CAll shells
DNucleus
Answer & Solution
Correct answer: B. Outermost shell
1. Valence electrons take part in chemical bonding.
2. They are the electrons in the outermost shell of the atom.
3. Their number decides the element's group and reactivity.
4. So valence electrons are in the outermost shell.
