Detailed explanation-1: -Carbon has 2 electrons in K-shell and 4 electrons in the L-shell which is an outermost shell. Therefore, the number of valence electrons is 4.
Detailed explanation-2: -Explanation: Carbon has four valence electrons in its outermost shell. Thus, its valency is four.
Detailed explanation-3: -Atomic carbon has six electrons: two inner shell (core) electrons in the 1s orbital, and four valence (outer most shell) electrons in the 2s and 2p orbitals.
Detailed explanation-4: -The atomic number of Carbon is 6. The electronic configuration of Carbon can be written as. The valence electrons are the sum of the electrons in the outermost shell, that is two electrons and two electrons which gives a total of four valence electrons.
Detailed explanation-5: -It cannot gain four electrons as a carbon atom has a total of 6 protons and is very small to handle ten electrons. It cannot even donate the electrons as it needs a lot of ionization energy to do so.
