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

Given: 

carbon atomic number = 6
