There are 55 particles in the nucleus of a mangan atom, of which 25 are protons. how many neutrons are in the nucleus

There are 55 particles in the nucleus of a mangan atom, of which 25 are protons. how many neutrons are in the nucleus and how many electrons revolve around the nucleus of this atom?

According to information from the school course of chemistry and physics, the nucleus of any atom contains as many electrons as protons. Accordingly, if the manganese nucleus contains 25 protons, then it also contains 25 electrons.

It is known that the number of neutrons is equal to the difference between the atomic mass of an atom and the number of protons. Therefore, since the atomic mass of manganese (from the condition) is 55, and the number of protons is 25, it turns out:

55 – 25 = 30 neutrons.

Answer: the nucleus of a manganese 55 atom contains 25 electrons and 30 neutrons.
