The respective electrons, valence electrons, and electron shells number of the structures in the above image are as follows:
- Structure 1: 18, 7, 3
- Structure 2: 2, 2, 1
- Structure 3: 9, 7, 2
What is valence electrons?
A valence electron is any of the electrons in the outermost shell of an atom; capable of forming bonds with other atoms.
An electron is the subatomic particle having a negative charge and orbiting the nucleus; the flow of electrons in a conductor constitutes electricity.
The electron shell is the collective states of all electrons in an atom having the same principal quantum number (visualized as an orbit in which the electrons move).
Therefore, the respective electrons, valence electrons, and electron shells number of the structures in the above image are as follows:
- Structure 1: 18, 7, 3
- Structure 2: 2, 2, 1
- Structure 3: 9, 7, 2
