Question
The outermost shell of an atom or an element is called:
- Group number
- Valency
- Valence electrons
- Electronic configuration
Hint:
The outermost shell is called as valence shell.
The correct answer is: Valency
- The electrons will be distributed in shells around the nucleus.
- The number of electrons in the outermost shell decides its ability of reactivity and bond formation.
- The outermost shell which has valence electrons are called as valence shell.
