Atomic Structure & the Periodic Table Basic Definitions Atom – smallest unit of an element that retains the properties of that element Atoms are made up of several subatomic particles called protons, neutrons, and electrons Protons, Neutrons, & Electrons Protons – have a +1 charge and are foun...
Chapter 5: Atomic Structure and the Periodic Table Early Models of Atoms Democritus (460-400B.C.) first suggested the existence of these particles, which he called “atoms” for the Greek word for “uncuttable”. They lacked experimental support due to the lack of scientific testing at the ...
