Question

State the collective name given to protons, neutrons in the nucleus of an atom.

2 Define the mass number.
3 An atom has atomic number of 28 and mass number of 64.
Find
1, Neutron number.
2, Proton number.
​

Answer 1

Answer: See explanation

Step-by-step explanation:

1. The collective name given to protons, neutrons in the nucleus of an atom is referred to as the nucleon.

2. The mass number simply means the total number of both the protons and the neutrons that we have in a nucleus.

3. Atomic number = Protons = 28

Mass number = 64.

Neutron = Mass Number - Protons

Neutron = 64 - 28 = 36

4. The number of Protons is also the number of atomic number which is 28.
