A fundamental particle usually found in the nucleus of an atom with a positive charge.(Basic Science/Radiography/subatomicparticles.htm)

the positive charge in the nucleus of an atom.

positively charged particles within the nucleus of an atom.

The positive charged particle in the nucleus of an atom.

The positively charged particles in the nuclei of atoms.

Sub-atomic particles with a positive charge and a relative mass of 1. Radioactivity

These are particles with a positive charge inside an atom. An atom is of neutral charge when the protons and orbiting electrons are present in equal numbers. (See also Electrons).

a positively charged subatomic particle. Protons, along with other subatomic particles called Neutrons, make up the nucleus of a atom. The number of protons in an atom is called the atomic number of the element. Compare to electrons.

A sub-atomic (really, really small) particle that carries a positive energy charge.

A proton is a small particle with a positive charge found in the nucleus of the atom. Classifying materials
