Atomic Theory Vocabulary

atom

• the basic particle from which all elements are made; the smallest particle of an element that has the properties of that element

• An idea that has been studied and investigated and is supported by a vast and diverse array of evidence

• A small, positively-charged particle that is found in the nucleus of an atom

• A tiny, negatively-charged particle that moves around the outside of the nucleus of an atom

electron
