Valency of an element in a compound refers to the number of electrons in the outermost shell of an atom that is involved in chemical bonding with another atom. The valency of barium in barium chloride can be calculated by using the chemical formula of the compound, which is BaCl2.

Barium Chloride Valency

  1. Step 1: Determine the number of electrons in the outermost shell of each element in the compound. Barium (Ba) has 2 electrons in its outermost shell, and chlorine (Cl) has 7 electrons.
  2. Step 2: Calculate the total number of electrons involved in bonding between the two elements. In BaCl2, there are 2 chloride ions, each with 7 electrons, so the total number of electrons involved in bonding is 7 x 2 = 14.
  3. Step 3: Subtract the number of bonding electrons from the number of electrons in the outermost shell of barium. The valency of barium in barium chloride is calculated as follows: 2 electrons in the outermost shell of barium - 14 bonding electrons = -12.
  4. Step 4: Determine the absolute value of the result. The absolute value of -12 is 12, so the valency of barium in barium chloride is 12.

Therefore, the valency of barium in barium chloride is 12.
