The valency of an element refers to the number of electrons it loses or gains in chemical reactions to form a chemical bond with another element.
To calculate the valency of magnesium, the following steps can be followed:
- Determine the number of electrons in the neutral atom: Magnesium (Mg) has 12 electrons in its neutral state.
- Determine the electron configuration of the ion: When magnesium reacts, it loses 2 electrons to form an ion with a charge of +2.
- Determine the valency: The valency of magnesium can be calculated as the charge on the ion, which in this case is +2.
Therefore, the valency of magnesium is +2.
