Why Argon has 22 neutrons?

How many protons neutrons and electrons are in 40 argon?

The three stable isotopes of Argon, Argon-36, Argon-38, and Argon-40, would all have 18 protons and 18 electrons if they are all neutral. The three isotopes will have different numbers of neutrons compared to each other (18, 20, and 22 neutrons respectively).

What is electron of argon?

The atomic number of argon is 18. That is, the number of electrons in argon is eighteen. Therefore, the argon atom will have two electrons in the first shell, eight in the 2nd orbit, and eight electrons in the 3rd shell.
