Question

How to find number of neutrons without knowing atomic mass and mass number? If you don't know atomic mass or mass number of an Element THEN how will you find Number of neutrons in the element

Answer 1

Answer:

hope it will help

Explanation:

This approximation of mass can be used to easily calculate how many neutrons an element has by simply subtracting the number of protons from the mass number. Protons and neutrons both weigh about one atomic mass unit or amu. Isotopes of the same element will have the same atomic number but different mass numbers.
