Select all that change when adding or subtracting a Proton Question 1 options:

Atomic Mass

Atomic Number

Charge

Which Element the atom is
I NEED ANSWER ASAP PLZ HELP!!!

Explanation:

To the atomic mass;

1.   Atomic mass is the number of protons + neutrons;

  When a new proton is added, the atomic mass increases.

   When a proton is removed, the atomic mass reduces

The mass of an atom is concentrated in the nucleus where there is the proton and neutron.

2. Atomic number is the number of protons:

When a new proton is added, the atomic number increases

When a new proton is removed, the atomic number reduces

3. Charge:

 An atom is neutral if the number of positive charges is the same as negative charges:

    Protons = electrons

If :

   Protons > electrons = +Ve charges

   Protons < electrons =  -Ve charges
