Respuesta :

An atom is made up of a nucleus (its center), protons, neutrons, and electrons
An atom has a couple basic parts:

Electrons: Negatively charged particles that orbit the nucleus 
Protons: Positively charged particles that lay in the nucleus
Neutrons: Particles with no charge and are found in the nucleus
The Nucleus: A mass of protons and neutrons that is at the center of each atom and which electrons orbit around.

Hope this helps!
