Valency of Nitrogen, Beryllium, and Magnesium

Nitrogen: The valency of nitrogen can vary depending on the compounds it forms. Nitrogen typically exhibits a valency of 3 or 5. In some compounds, it can also exhibit a valency of 1 or 2. For example, in ammonia (NH3), nitrogen has a valency of 3, while in nitrogen dioxide (NO2), it has a valency of 4. In the case of nitrogen gas (N2), the valency is 3. The valency of nitrogen can range from 1 to 5 depending on the compound it is part of.

Beryllium: Beryllium typically exhibits a valency of 2. This means that it can form compounds by donating its two valence electrons. Beryllium's valency is consistent across most of its compounds, making it relatively predictable in chemical reactions. The valency of beryllium is 2.

Magnesium: Magnesium typically exhibits a valency of 2. This means that it can lose two electrons to form compounds. In most of its compounds, magnesium displays a valency of 2, making it similar to beryllium in this regard. The valency of magnesium is 2.

In summary, the valency of nitrogen can range from 1 to 5 depending on the compound, while beryllium and magnesium typically exhibit a valency of 2.
