Verified step by step guidance1
Recall that the number of protons in a neutral atom is equal to the atomic number of the element.
Identify the element given in the problem, which is chlorine.
Look up the atomic number of chlorine on the periodic table; this number represents the number of protons.
Understand that the atomic number is unique to each element and defines the number of protons in its nucleus.
Conclude that the number of protons in a neutral chlorine atom is equal to chlorine's atomic number.
