The correct answer is (a) 11.
· The atomic number of an atom represents the number of protons in its nucleus. Since the atomic number of this atom is 11, it means the atom has 11 protons.
Information Booster:
· Mass number is the sum of the number of protons and neutrons in the nucleus. In this case, the mass number is 23.
· The number of neutrons can be calculated by subtracting the atomic number from the mass number:
Neutrons=23−11=12
