Q:

How big is a proton?

A:

Quick Answer

A proton is a positively charged particle that is approximately 1.67*10^-27 kilograms in size. Protons can also be measured in Mega-Electron Volts. In Mega-Electron Volts, a proton is approximately equal to 938.27.

Full Answer

A proton is roughly the same size as a neutron, but it is much larger than its negative counterpart, the electron. In an atom, protons and neutrons stick together to make up the nucleus at the center of the atom. Electrons float around the nucleus in orbits. In total, atoms are comprised of electrons, protons and neutrons. Each atom has a different number of each of these microscopic particles.

    What is the charge of a proton?

    A:

    A proton is a subatomic particle that has a positive charge of +1 e. An "e" is defined as the elementary electrical charge that a proton possesses, measured at approximately 1.6 x 10^-19 coulombs. The positive electrical charge of a proton is opposed by negative charge of an electron.

  • Q:

    Why do ions form?

    A:

    Ions are positively or negatively charged particles that form as a result of an atom losing an electron or gaining a proton. Ions form when metals react with nonmetals and exchange protons or electrons. In an ionized particle, the number of protons is not equal to the number of electrons.
