Fichas del conjunto (8)
- 1_____ are the smallest particles of an element that can take part in chemical reactions.Atoms.
- 2Atoms are made of three types of subatomic particle.Protons and Neutrons (In the nucleus) and electrons (In the shells/ energy levels)
- 3The ______ is 20,000 times smaller than the atom its selfNucleus
- 4Subatomic particles have very, very small masses and electrical charges. its more convenient to describe their masses and charges compared to a proton.These are called the particles relative mass and relative charge
