Bond Order and Charge per Oxygen Atom on HSO4-

Bond Order
The bond order of a molecule is defined as the number of chemical bonds between a pair of atoms. In the case of HSO4-, the bond order can be calculated by counting the number of bonds between the atoms and dividing by the number of bond pairs. In HSO4-, there are four oxygen atoms, one sulfur atom, and one hydrogen atom.

The sulfur atom is bonded to four oxygen atoms, and each of these bonds is a double bond. Therefore, the total number of bonds in the molecule is eight. Dividing this number by the total number of bond pairs (12), we get a bond order of 8/12 or 2/3.

Charge per Oxygen Atom
The charge per oxygen atom in HSO4- can be calculated by dividing the total charge of the molecule by the number of oxygen atoms. The total charge of HSO4- is -1, which is due to the extra electron on the sulfur atom.

There are four oxygen atoms in HSO4-. Dividing the total charge of -1 by the number of oxygen atoms (4), we get a charge of -1/4 or -0.25 per oxygen atom.

In conclusion, the bond order of HSO4- is 2/3, and the charge per oxygen atom is -0.25. These values are important in understanding the chemical properties and behavior of the molecule.
