Valence electrons are those electrons that are furthest from the nucleus. They are involved in chemical bonding and determine the reactivity of an atom. Therefore, the correct statement is:
They are those electrons that are furthest from the nucleus.
The other statements are incorrect:
- Valence electrons are not found in the nucleus.
- Valence electrons are negatively charged, not neutrally charged.
- While they may be in the outermost shell, they are not characterized by being "closest" to the nucleus.
