The valency of aluminum (Al) can be calculated using the following steps:

  1. Determine the electron configuration of aluminum: The electron configuration of aluminum is [Ne] 3s2 3p1, where [Ne] represents the electron configuration of a neutral neon atom.
  2. Identify the number of electrons in the outermost shell: The outermost shell of aluminum is the third shell, and it contains three electrons (3s2 3p1).
  3. Calculate the valency: The valency of an element is the number of electrons it can gain, lose, or share to complete its outermost shell. In the case of aluminum, it has three electrons in its outermost shell, which means it needs to gain three electrons to complete its shell. Therefore, the valency of aluminum is 3.

In conclusion, the valency of aluminum is 3, as it can form three bonds with other elements in order to complete its outermost shell.
