Question

Which equation below would you use to determine the number of neutrons in a given nucleus when you are given the atomic number (Z) and atomic mass (A)?

N = A + Z
N = A/Z
N = AZ
N = A – Z

Answer 1

A-Z

Step-by-step explanation:

A proton has an estimated weight of 1.

Answer 2

N = A - Z

Step-by-step explanation:

Atomic number is the number of protons in a nucleus

Atomic mass is the number of protons and neutrons

N will be give when you subtract A from Z giving you the number of neutrons

hope this helps thx
