BRAINLIESTTT PLEASE ANSWER :)

An atom with 5 protons, 6 neutrons, and 5 electrons has an atomic mass of _____ amu. (Enter a whole number.)

Respuesta :

The answer is 11 Amu
Yes it is 11 atomic mass units (amu). Atomic mass (aka mass number) is asking "what is the weight of the nucleus?"
The nucleus contains all of the protons and neutrons, thus:
atomic mass = P + N = 5 + 6 = 11 amu
