The video tutorial explains valency as the combining capacity of an element, focusing on Group 4 elements, which have a valency of four due to their electronic configuration. Carbon, a Group 4 element, forms four covalent bonds to achieve a stable octet configuration, as seen in compounds like methane and carbon dioxide. The video also discusses the challenges in forming carbon anions due to carbon's low electronegativity and the inability of its nucleus to hold additional electrons.
