Question

relationship between atomic number and atomic mass​

Answer 1

Answer:

Together, the number of protons and the number of neutrons determine an element's mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.

Answer 2

Answer:

Yes

Explanation:

Atomic mass is twice the atomic number for elements with even atomic number. And atomic mass is twice plus one for elements with odd atomic number. Exception case for nitrogen where atomic number equal to 7 and atomic mass equal to 14.
