Answer 2

Element Valency Based on Given Formulas

The valency of an element is its combining power with other elements, and it is determined by the number of electrons in the outermost shell of the atom. Let's analyze the valency of the elements based on the given formulas.

- I (Iodine): Iodine typically has a valency of -1 when it forms compounds. - II (Calcium): Calcium typically has a valency of +2 when it forms compounds. - IV (Tin): Tin can exhibit different valencies, but in the given formula "SnO," it has a valency of +4. - V (Nitrogen): Nitrogen typically has a valency of -3 or +5 when it forms compounds. In the given formula "NO," nitrogen has a valency of +2. - VI (Sulfur): Sulfur typically has a valency of -2 or +6 when it forms compounds. In the given formula "SO," sulfur has a valency of +4.

Therefore, based on the given formulas: - I (Iodine): -1 - II (Calcium): +2 - IV (Tin): +4 - V (Nitrogen): +2 - VI (Sulfur): +4
