Answer:

2 electrons

Step-by-step explanation:

A neutral atom is one in which the number of protons is equal to the number of electrons, which makes it electrically neutral. As the question above does not specify that the atom is not neutral, we can confirm that its electron number is equal to the number of protons.

In these cases, the neutral atoms have no charge, that is, they have a neutral charge. Together with protons, it is part of the atomic nucleus, responsible for almost the entire mass (99.9%) of the atom.
