Located within the nucleus of the atom, a proton has a relatively larger mass than that of an electron but slightly smaller than that of a neutron. A proton will always have at least one positive charge. The proton is responsible for the atom's atomic number. The positive proton charge ba...
What are the 3 parts of an atom? An atom of an element has 10 protons. what is also true of that atom? What are atoms and elements, and how do they differ? What is the atomic mass of an atom that has 6 protons, 6 neutrons, and 6 electrons?
Find the nucleus. The nucleus of an atom is always right smack dab in the middle of any atom, like the sun is in the middle of the solar system (but don't take that analogy too far). The nucleus is very dense and compact, and while it can have just one particle (a single proton...

The electrons in an atom are attracted to the protons in the nucleus by the electromagnetic force. Electrons can escape from their orbit, but only in response to an external source of energy being applied. The closer orbit of the electron to the nucleus, the greater the attractive force; hen...
