* Atomic Number: Chlorine's atomic number is 17. This means a neutral chlorine atom has 17 protons.
* Neutral Atoms: In a neutral atom, the number of protons (positive charge) is equal to the number of electrons (negative charge).
Therefore, chlorine-35 has 17 electrons.
Important Note: The number "35" in chlorine-35 refers to the mass number, which is the total number of protons and neutrons in the atom. The number of electrons is determined by the atomic number, not the mass number.
