Given an Atom with:
Mass Number = 23
Atomic Number = 11
Determine the number of protons in the atom.
Explanation:
In order to determine the number of protons that the atom has, we simply look back at the concepts concerning the atom.
Mass Number = Atomic Number + Number of Neutrons
Atomic Number = Number of Protons = Number of Electrons
Number of Neutrons = Mass Number - Atomic Number
It can be seen that the number of protons is equal to the atomic number of the atom, therefore,
Number of Protons = 11
Final Answer:
Number of Protons = 11
