Why do elements in group 4A do not form ionic bonds?

Why elements of V111 A, have zero electronegativity?

Solutions

Expert Solution

The group IV A or 14 is carbon family. The valence shell electronic configuration is . The number of valence electrons is 4. The sum of first four ionization enthalpies is very high. It is very difficult to remove all four valence electrons. Hence, elements in group 4A do not form ionic bonds. They share electrons and form covalent bonds.

The elements of VIII A or 18 are called noble elements or inert gases. They have completed their octet. They have stable electronic configuration. They are chemically unreactive and do not participate in bond formation. They have no tendency to attract shared pair of electrons. Hence, elements of VIII A or 18, have zero electronegativity
