Beryllium has 4 protons and normally 4 neutrons in its nucleus. It usually has 4 electrons orbiting that nucleus, but this number can change depending on its level of ionisation.
Protons are found in nucleus, as neutrons are also.
Protons and Electrons are actually quite different. Protons have a positive electric charge, while electrons have a negative electric charge. Atoms usually have the same number of protons and electrons, which means they balance each other out giving a neutral electric charge. If there are more of either protons or electrons, the atom will have an overall charge. (Negative or Positive). Protons are also located in the nucleus with the neutrons, while electrons are located in the outer shells surrounding the nucleus.
they both show particles but an atomic number is the amount of protons in the nucleus and a dot diagram is to show the bonding of atoms with electrons. and does not show the amount of electrons those atoms have but the valence electrons each atom has

TRUE
In this model, the electrons move or orbit around the protons that are at the center of the atom. Electrons move around the nucleus, which contains the proton, in orbits that have a definite size and energy.

The number of protons is usually the same as the number of electrons!:)

Protons and neutrons are found in the nucleus, but electrons surround the nucleus. (Electron cloud.)
The electrons "orbit" the nucleus of an atom. They do so because they are attracted to the positive charge of the protons inside the nucleus. They do not usually leave the atom because of this attraction, and do not usually fall into the nucleus because they are moving.
An atom has a nucleus composed of protons and usually neutrons as well (there is only one kind of atom which has no neutrons, which is the hydrogen 1 isotope) and it also has electrons surrounding the nucleus, with the same number of electrons as the number of protons in the neutrons.

None. The electrons are not in the nucleus for any atoms. They swirl around the nucleus in space but do not enter the nucleus. If electrons are squeezed into nuclei of atoms through gravity in supermassive star collapses, they fuse with protons and become neutrons. Sodium has 11 protons and usually 12 neutrons in their nuclei but no electrons.
