hey mate ☺️☺️☺️☺️☺️☺️
__________
⏸️Valency is the number of free electron/electrons in the outermost shell of an element. The greatest valency could be 4.
⏺️when the valency of an element is 4 it can neither lose nor accept 4 electrons to form an ionic bond , because it would be difficult for nucleus with six protons to hold on to ten electrons, that is four extra electrons.(take in case of carbon with valency 4).
⏏️also it would require a large amount of energy to remove four electrons leaving behind a carbon cation with six protons in its nucleus holding on to just two electrons!
⏸️ I hope it will help you ✌️✌️✌️
