How many atoms of each element does potassium nitrate (KNO3) contain?

A. Potassium = 3 atom, Nitrogen = 3 atom, Oxygen = 3 atoms

B. Potassium = 3 atom, Nitrogen = 1 atom, Oxygen = 3 atoms

C. Potassium = 1 atom, Nitrogen = 3 atom, Oxygen = 3 atoms

D. Potassium = 1 atom, Nitrogen = 1 atom, Oxygen = 3 atoms


Answer :

The correct option is D. Potassium = 1 atom, Nitrogen = 1 atom, Oxygen = 3 atoms

Explanation:

Potassium nitrate can be described as a chemical compound which is anionic salt. It has positive K+ ions and negative NO3- ions.

  1. The formula shows that there is only one atom of potassium element.
  2. The formula shows that there is one atom of nitrogen element present in potassium nitrate.
  3. As we can see, the number 3 is written after O. This shows that there are 3 atoms of oxygen present in the compound potassium nitrate.
