What’s the difference in the number of protons of an atom of lithium and an atom of chlorine :)) I need this answer quick

14

Explanation:

The lithium atom has 3, which is its atomic number. (Atomic number is the number of protons in the nucleus of an atom, which determines the chemical properties of an element and its place in the periodic table.) The chlorine atom has 17, so if you find the difference, it would be 14.
