A lot of information about the nucleus and the atom can be drawn from this. Consider an element AXZ. Based on this information, answer the question that follow.
What is the no. of protons in this element?
Answer & explanation
Correct answer: option 4
Mass no. = No. of Protons + No. of Neutrons
Atomic No. = No. of Protons
A = Z + No. of Neutrons
