Questions 5
Topics Electron, Endoskeleton, Proton, Radiation, Stomach

Study Guide

Electron

An electron is a subatomic particle that orbits the nucleus of an atom. It carries a negative electric charge. Generally, an atom has the same number of negative electrons orbiting the nucleus as it does positive protons inside.

Endoskeleton

An endoskeleton (internal skeleton) is a charateristic of vertebrate animals, including humans.

Proton

A proton is a subatomic particle found in the nucleus of an atom. It carries a positive electric charge.

Radiation
