To determine the charge that each atom will make when it bonds with other atoms, we need to look at the periodic table and find the group or column number of each element.
1. Calcium (Ca) is in Group 2, so it forms a 2+ charge when it bonds. The correct answer is h) +2.
2. Francium (Fr) is in Group 1, so it forms a 1+ charge when it bonds. The correct answer is c) +1.
3. Bromine (Br) is in Group 17, so it forms a 1- charge when it bonds. The correct answer is a) -1.
4. Sulfur (S) is in Group 16, so it forms a 2- charge when it bonds. The correct answer is e) -2.
5. Xenon (Xe) is a noble gas, which means it rarely forms bonds and usually has a charge of 0. The correct answer is g) 0.
6. Carbon (C) is in Group 14, so it generally forms a 4- charge or a 4+ charge when it bonds. The correct answer is f) +4/-4.
7. Phosphorus (P) is in Group 15, so it forms a 3- charge when it bonds. The correct answer is d) -3.
8. Boron (B) is in Group 13, so it forms a 3+ charge when it bonds. The correct answer is b) +3.
By matching the elements in Column A with their corresponding charges in Column B, we can determine the charge each atom will make when it bonds with other atoms.
