Problem: Chlorine has two naturally occurring isotopes, 35Cl and 37Cl. What is the mass number of each isotope? How many protons, neutrons, and electrons are present in each?

FREE Expert Solution

An element can be represented as:


You can determine the identity of the element using its atomic number:

Atomic number (Z): 

represents the identity of the element
reveals the number of protons
in a neutral element:

            # of protons = # of electrons

Mass number (A)

reveals the number of protons and neutrons

            mass number = # of protons + # of neutrons
