Metals
A pure substance that contains only one kind of atom
Element
A pure substance that contains more than one kind of atom
Compound
Compound containing a metal and non-metal
Ionic (ionic bonds)
Compound containing two non-metals
Molecular (covalent bonds)
Aqueous substances containing hydrogen (H+)
Acid
Aqueous substances containing hydroxide (OH-)
Base
Mixtures that are uniform throughout
Homogenous
Mixtures that are non-uniform throughout
Heterogenous
Smallest particle that can be defined as an element
Atom
Negatively charged subatomic particle
Electron
Subatomic particle that defines the element
Proton
Single particle or group of particles having a net charge
Ion
Neutrally charged subatomic particle
Neutron
Scientist responsible for the billard ball analogy
Dalton
Scientist responsible for the raisin bun analogy
Thomson
Scientist responsible for the Gold Foil experiment and discovering the nucleus
Rutherford
Science responsible for the concept of electron energy levels
Bohr
The part of the atom that contains protons and neutrons
Nucleus
Atoms of the same element that have different numbers of neutrons
Isotopes
The atomic number tells the number of these subatomic particles
Proton
How the number of neutrons can be found
Mass Number ( - protons)
All elements in group one have the same number of these
Valence electrons
All elements in period one have the same number of these
Occupied energy levels (valence shells)
Positively charged ions
Cations
Negatively charged ions
Anions
Turns blue litmus red
Acid
Turns red litmus blue
Base
Energy given off during a reaction
Exothermic
Energy consumed during a reaction
Endothermic
