Solution

Sure, here are the steps to calculate the number of pairs of electrons for the compound PCl5:

  1. Identify the number of valence electrons for each atom in the compound. Phosphorus (P) has 5 valence electrons and Chlorine (Cl) has 7 valence electrons.

  2. Multiply the number of Chlorine atoms by the number of valence electrons. In PCl5, there are 5 Chlorine atoms, so 5 Cl * 7 e- = 35 electrons.

  3. Add the number of valence electrons from Phosphorus. So, 35 e- (from Cl) + 5 e- (from P) = 40 electrons.

  4. Since a pair of electrons consists of 2 electrons, divide the total number of electrons by 2 to get the number of pairs. So, 40 e- / 2 = 20 pairs of electrons.

So, the compound PCl5 has 20 pairs of electrons.
