What is the difference between 35cl and 37cl

The number of protons an atom has, also known as the atom's atomic number , determines which element it is. All atoms which contain 17 protons are called chlorine atoms.

Adding or removing a proton from an atom's nucleus changes that atom's atomic number and creates a different element. Chlorine and chlorine are both isotopes of the element chlorine. The number after the name 'chlorine' is called the mass number.

The mass number is a tally of the number of protons and the number of neutrons in an atom's nucleus. Since all atoms of chlorine contain 17 protons, chlorine and chlorine differ in the number of neutrons each one has. Sign up or log in Sign up using Google. Sign up using Facebook.
