Question

Match the following terms to the correct element.

Column A
1.
Sulfur (S):
Sulfur (S)
2.
Sodium (Na):
Sodium (Na)
3.
Calcium (Ca):
Calcium (Ca)
4.
Carbon (C):
Carbon (C)
Column B
a.6 valence electrons
b.1 valence electron
c.4th period
d.4th group.

Answer 1

Here’s the matching for the terms in Column A to the corresponding descriptions in Column B:

1. **Sulfur (S)**: **a. 6 valence electrons**
2. **Sodium (Na)**: **b. 1 valence electron**
3. **Calcium (Ca)**: **c. 4th period**
4. **Carbon (C)**: **d. 4th group**

So the matched pairs are:
- Sulfur (S) - a
- Sodium (Na) - b
- Calcium (Ca) - c
- Carbon (C) - d
