Question

ANSWER PLSSSSSSSSSSSSSS YOU GET 10 POINTS BC I SELECTED 15!

Answer 1

The answer would be 13.

To find the atomic mass of a atom, you would add the number of protons and the number of neutrons together. Electrons don't take up much or any of the mass of an atom.

(number of protons) + (number of neutrons) = 7 + 6 = 13

The answer would be 13.

I hope this helps.

Answer 2

Each proton and each neutron weight one atomic mass unit (amu)

Therefore, your answer is 6+7=13

13 amu
