Answer: Option C) The Atomic number is 13
Explanation:
The number of neutrons + Protrons = Atomic Mass
Thus, 15 + Protrons = 28
Protrons = 28 - 15 = 13
Usually, the number of protons in an atom is always EQUAL to the Atomic number of the atom
Since number of protons is 13, therefore the atomic number of the given atom is 13
