Energy
Heat - 3MassMass is a measure of how much matter is in an object. Mass is often measured in kg's. The formula for mass is
Mass=Volume * Density - 4VolumeThe three dimensional space occupied by a substance. The formula for volume is
Volume=mass/density - 5Atomic StructureAtoms are made up of protons, neutrons, and electrons
- 6ProtonPositive particle in the nucleus of an atom
Relative Mass: 1836
Relative Charge: 1+ - 7NeutronsNeutral particle in the nucleus of an atom
Relative Mass: 1839
Relative Charge: none - 8ElectronsNegative particles surrounding the nucleus of an atom.
Relative Mass: 1
Relative Charge:1- - 9Alkali MetalLithium, Sodium, Potassium, Rubidium, Cesium, Francium
- 10Alkaline Earth MetalsBeryllium, Magnesium, Calcium, Strontium, Barium, Radium
- 11Boron FamilyBoron, Aluminum, Gallium, Indium, Thallium
- 12Carbon FamilyCarbon, Silicon, Germanium, Tin, Lead
- 13Nitrogen FamilyNitrogen, Phosphorus, Arsenic, Antimony, Bismuth
- 14Oxygen FamilyOxygen, Sulfur, Selenium, Tellurium, Polonium
- 15HalogensFluorine, Chlorine, Bromine, Iodine, Astatine
- 16Noble GasesHelium, Neon, Argon, Krypton, Xenon, Radon
- 17Atomic Number# of protons and also the # of electrons
- 18Atomic Mass# of protons + #of neutrons
- 19IsotopesAtoms with the same numbers of protons but different numbers of neutrons
- 20Isotopes pertaining to the atomic massthe sum of the protons and neutrons in the nucleus of the atom will differ
- 21Groups (families)display similar chemical characteristics because the number of valence n the electrons is the same within a group
- 22Metalsmost of the elements on the periodic table are metals
- 23Valence ShellOutermost shell, for electrons
- 24NonmetalsMost are gases at room temperature except bromine
- 25Metalloids (semimetals)have a mixture of metallic and nonmetallic properties
Boron, Silicon, Germanium, Arsenic, Antimony, Tellurium, Polonium, Astatine - 26Diatomic MoleculesThese molecules only exist in the monoatomic state when they are by themselves:
Br, I, N, Cl, H, O, F
brinclhof - 27IonsIons are atoms with extra electrons or missing electrons.
- 28Cationa cation is a positively charged ion.
Metals lose electrons and form cations (+) when you have a (+) you will subtract an electron - 29Anionan anion is a negatively charged ion. nonmetals gain electrons and form anions (-) (when you have a minus, you add an electron)
- 30Percent AbundanceHow often a certain isotope occurs in nature
- 31Ionic bondsmetals are cations + and on metals are anions- which when combined form ionic bonds
- 32Ionic CompoundA compound that is formed by a metal and a non metal coming together. metals are cations non metals are anions.
- 33Covalent BondingResulting bond when sharing the outermost valence electrons. 2 or more nonmetals (nonmetals are on the far righthand side of the periodic table). The first element does not need a mono in front of it.
