Question

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 1

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.

• The formula shows that there is only one atom of potassium element.

• The formula shows that there is one atom of nitrogen element present in potassium nitrate.

• 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.
