The atomic number of chlorine is 17.

The atomic weight (after the IUPAC rules weight is the correct word in this

case, for elements, not mass; mass is used only for isotopes) of chlorine is

[35,446; 35,457], after the IUPAC tables, 2009 edition.

Why does chlorine have a mass number of 35.5?

Chlorine has a mass number of 35.5 because it is a mixture of two stable isotopes, chlorine-35 and chlorine-37. The average atomic mass of chlorine is calculated by taking into account the abundance of each isotope in nature. The weighted average of these isotopes gives the atomic mass value of 35.5 for chlorine.


Chlorine with mass number-35 and a atomic number-17 and Chlorine with mass number-37 and a atomic number-17 How do they know that they are the same element?

Atomic number is unique to an element. Since both Chlorine-35 and Chlorine-37 has atomic number of 17, they are both Chlorine. However they have different atomic mass (caused by different number of neutrons in the atom) thus they are called isotope.

Atomic mass is 35.453?

Yes, atomic mass refers to the average mass of an element's atoms, including all isotopes. The value of 35.453 likely refers to the atomic mass of chlorine, which is the average mass of all naturally occurring isotopes of chlorine.
