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: -Carbon has four valence electrons, so it can achieve a full outer energy level by forming four covalent bonds. When it bonds only with hydrogen, it forms compounds called hydrocarbons. Carbon can form single, double, or triple covalent bonds with other carbon atoms.
Detailed explanation-3: -Therefore, the valency of carbon is just 4 .
Detailed explanation-4: -What is the valency of carbon? Explanation: Carbon has four valence electrons in its outermost shell. Thus, its valency is four.
Detailed explanation-5: -It has to either lose or gain 4 electrons in order to gain a stable electronic configuration. 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.
