Atomic Structure

Electrons have a relative weight of approximately 1/1836, which is negligible compared to protons and neutrons.

The atomic mass tells you the total number of subatomic particles (protons and neutrons) in the nucleus of an atom.

An isotope is formed when the number of neutrons in an atom changes.

Electrons are negatively charged particles.

Yes, changing the number of neutrons changes an atom's mass.

Protons are positively charged subatomic particles found in the nucleus of an atom.

The atomic number is the number of protons in the nucleus of an atom, which determines the element's identity.

The mass number is the total number of protons and neutrons in an atom's nucleus.

Neutrons are neutral subatomic particles found in the nucleus of an atom.

An ion is an atom that has gained or lost one or more electrons, resulting in a net charge.
