Here are the charges for each of the listed atoms when they typically bond with other atoms:

  1. Calcium (Ca): a. +2 (as it is an alkaline earth metal)
  2. Francium (Fr): e. +1 (as it is an alkali metal)
  3. Bromine (Br): c. -1 (as it typically forms anions)
  4. Sulfur (S): g. -2 (as it commonly gains two electrons)
  5. Xenon (Xe): f. 0 (as it is a noble gas and typically does not form bonds)
  6. Carbon (C): h. +4/-4 (as it can either lose 4 electrons to form positive ions or gain 4 to form negative ions)
  7. Phosphorous (P): d. -3 (it commonly gains three electrons)
  8. Boron (B): b. +3 (as it is a metalloid and typically loses three electrons)

Here’s a summary:

  1. Calcium (Ca): +2
  2. Francium (Fr): +1
  3. Bromine (Br): -1
  4. Sulfur (S): -2
  5. Xenon (Xe): 0
  6. Carbon (C): +4/-4
  7. Phosphorous (P): -3
  8. Boron (B): +3
