The mass and the charge.
Protons are positively charged. Electrons are negatively charged. Neutrons have no charge.
Protons and neutrons have similar mass (about 1 amu).
The mass of electron is about 1822 times less than that of protons / neutrons.
The subatomic particle that defines the element is the proton. The number of protons in the nucleus of an atom determines the element's atomic number, which differentiates one element from another on the periodic table.
A colloid is not a subatomic particle.
protons and neutrons are about 1 amu
The lightest subatomic particle is the electron.
The subatomic particle that has no charge is a neutron.
The subatomic particle with a negative charge is the electron.
A negatively charged subatomic particle is an electron, or the antiproton.
The electron is the subatomic particle with a negative charge.
The electron is a subatomic particle that has a charge of -1.
The number of neutrons is different for each isotope.
The number of neutrons is different for each isotope.
