REDOX EQUILIBRIA SL - chemistryatdulwich
... When metals react they lose electrons or are oxidized, when non-metals react they gain electrons or are reduced. Therefore the reactivity of a metal or non-metal is about how easily it is oxidized or reduced or how strong a reducing or oxidizing agent it is. The strength of an oxidising or reducing ...

Section 1 Development of the Atomic Theory
... Although it was a long time before most people agreed that matter was made of atoms, Democritus was right in an important way. We now know that matter is made of particles that we call atoms. An atom is the smallest particle into which an element can be divided and still have the properties of that ...
