What element has 18 protons?

The element that has 18 neutrons is ARGON... Wow, why didn't look in a periodic table? Is easier ask here??? Actually, 18 is argon's atomic number, and it also has 18 protons and electrons.. but it has 22 neutrons. The number of neutrons = mass number - number of protons. Soo, the answer is Chlorine, 17 protons, 17 electrons and 18 neutrons
