Answer:
The three main subatomic particles that form an atom are protons, neutrons, and electrons. The center of the atom is called the nucleus. First, let's learn a bit about protons and neutrons, and then we will talk about electrons a little later. Protons and neutrons make up the nucleus of an atom. We know that protons are positively charged and neutrons are neutral particle. A combination of positively charged and neutral particles would definitely form positively charged particle. So, nucleus has net positive charge. The magnitude of charge of nucleus is equal to the number of protons present in it.
Explanation:
Atoms consist of three basic particles: protons, electrons, and neutrons. The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged).
