3.
Bromine (Br):
Bromine (Br)
4.
Sulfur (S):
Sulfur (S)
5.
Xenon (Xe):
Xenon (Xe)
6.
Carbon (C):
Carbon (C)
7.
Phosphorous (P):
Phosphorous (P)
8.
Boron (B):
Boron (B)
Column B
a.+2
b.+3
c.-1
d.-3
e.+1
f.0
g.-2
h.+4/-4

Answer 1

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**
