elements
1. Na (sodium)
2. Mg (magnesium)
3. O (oxygen)
4. N (nitrogen)
5. Cl (chlorine)
6. Ne (neon)
7. C (carbon)
8. Al (aluminum)
number of valence electrons
a.6
b.3
c.1
d.2
e.4
f.8
g.7
h.5

Answer 1

Here are the matches for the elements to the number of valence electrons they have:

1. Na (sodium) - c.1
2. Mg (magnesium) - d.2
3. O (oxygen) - a.6
4. N (nitrogen) - h.5
5. Cl (chlorine) - g.7
6. Ne (neon) - f.8
7. C (carbon) - e.4
8. Al (aluminum) - b.3

So, the final matches are:
- Na → 1
- Mg → 2
- O → 6
- N → 5
- Cl → 7
- Ne → 8
- C → 4
- Al → 3
