Answer:
Zirconium
Explanation:
Given that,
Mass number = 92
No of neutrons = 52
Mass number is the sum of the number of protons and neutrons. We can find the number of protons.
92 = 52 + P
P = 40
Atomic number is equal to the number of protons. It means that the atomic no of the element is 40. The element is Zirconium whose atomic number is 40 and mass number is 92.
