Proton
positive charge, found in the nucleus, contribute to the mass and identity of an atom
Neutron
neutral charge, found in the nucleus, contributes to the mass of an atom
electrons
negative charge, found in the electron cloud, determines properties of the atom
What force keep the electrons from flying away?
The electromagnetic force, states that opposite charges attract like protons and electrons and the nucleus is + and the electron cloud is negative so they stay together.
What force keeps the nucleus from repelling?
The strong nucleus force, Protons and neutrons are made up of quarks which is stronger than the electromagnetic force meaning they stay together.
Why aren’t electrons held tight to the nucleus?
They aren’t held tight because electrons don’t have quarks meaning that they are not affected by the strong nucleus force
