Electrons in last orbit of atom are known as
- Free electrons
- Valence electrons
- Bound electrons
- None of above
Correct answer: 2. Valence electrons
Explanation: Valence electrons are the electrons in the outermost energy level (or orbit) of an atom. These electrons are involved in the formation of chemical bonds and are crucial in determining the chemical properties of an element. The number of valence electrons largely influences an element’s reactivity and ability to combine with other elements.
