The number of sodium atoms that are in one formula unit of sodium nitrate is: one (1).
Sodium is a chemical element that is found in group 1 of the periodic table because it has one (1) electron in its outermost shell.
This ultimately implies that, sodium has an atomic number of one (1) and it typically requires loosing a single (one) valence electron to reach a full octet state.
Sodium nitrate is a white, poisonous, crystalline chemical compound with the chemical formula [tex]NaNO_3[/tex].
From this formula unit of sodium nitrate, we can deduce the following points:
- It contains one (1) atom of sodium.
- It contains a single (1) atom of nitrogen.
- It contains three (3) atoms of oxygen.
In conclusion, one formula unit of sodium nitrate contains a single (1) atom of sodium.
