Detailed explanation-1: -Tin’s valency can be represented as 4 since the outermost shell only has 4 electrons.
Detailed explanation-2: -Tin is located in the group 14 of the periodic table, which means that it has four electrons in its outermost shell, i.e. four valence electrons.
Detailed explanation-3: -Carbon has a valency of four, so it is capable of bonding with four other atoms of carbon or atoms of some other monovalent element. This is known as tetravalency of carbon.
Detailed explanation-4: -Some elements have different capacities to combine with different elements. This depends on the nature of reaction. This property of having different capacity to combine with different elements is called variable valency. For example in ferrous oxide valency of iron is +2, whereas in ferric oxide valency of iron is +3.
