The electrons on the outermost energy level of the atom are called valence electrons. The valence electrons are involved in bonding one atom to another. The attraction of each atomâs nucleus for the valence electrons of the other atom pulls the atoms together. As the attractions bring the atoms together, electrons from each atom are attracted to the nucleus of both atoms, which âshareâ the electrons.
Metal. Valency: Since there are 4 electrons in the valence shell, they can make use of these electrons in the bond formation to get octet configuration. Hence their usual valency is 4. However the group 14 elements other than carbon can also show the maximum valency 6 due to the presence of available d-orbitals in them. But carbons maximum valence is 4 due to non availability of d-orbitals. Oxidation number: Their usual stable oxidation number is +4.
