Respuesta :
The mass of an atom comes from the protons and neutrons that are found in the nucleus. The number of protons is the atomic number of an element. To find the number of neutrons, subtract the atomic number from the mass of an atom. So, if an element is 76, the number of protons AND electrons is also 76.
Answer:
D
Explanation:
Considering that this is a neutral atom, the amount of protons and electrons are going to be equal :))
