- 1
- 2
- 3
- 4
Hint:
Valence electrons are the electrons of the outermost shell.
The correct answer is: 4
- The atomic number of carbon is 6. This means it has 6 electrons.
- Electrons are arranged in the shells following the principle of electron filling.
- The arrangement of electrons in carbon looks like 2,4.
- Valence electrons are the electrons present in the outermost shell. In carbon number of valence electrons is 4.
