Can you identify an atom without knowing number of neutrons in it?
Yes, and in order to find the Number of Neutrons, subtract Atomic Mass from Number Of Protons, the result will be the Number of Neutrons for that atom *No. Of Neutron=Atomic Mass - Number Of Protons

An atom with a mass number of 45 has three more neutrons than protons What is the atomic number of this atom?
The atomic number is 21: The mass number is the sum of protons and neutrons, while the atomic number is the number of protons, designated n. From the statement of the problem, n+n+3 = 45, or 2n = 42, or n=21.
