Elements: are pure matter whose smallest particles are either atoms or molecules
Compounds: are pure matter whose smallest particles are molecules
Mixture: is matter that consist of two or more kinds of pure substances that are not chemically combined
Atom: is the basic unit of an element
Solid: has definite shape and volume
Liquid: has definite volume but no definite shape
Gas: has no definite shape and volume
Melting: change from solid to liquid
Protons: are the subatomic located in the nucleus of an atom
Vaporization: liquid to gas
Sublimation: change of solid to gas
Freezing: is the change of liquid to solid
Plasma: is also a physical state, but requires a special condition to exist
Periodictable: it is an organized listing of elements that helps us predict the behavior of element in an chemical reactions
Period: a single horizontal row in the periodic table
Group: the vertical row that has physical and chemical properties
Alkalimetals: soft, shiny metals with high ductility, relatively low melting point and excellent conductor of electricity
Halogen: exist as combination of 2 atoms forming diatomic molecules
Noblegas: these are quite unreactive elements
Ions: a charge particles
CovalentBond: when outer electrons in each atoms are shared by two atoms
Ioniccompound: Compounds formed by the transfer of electrons between groups of atom
Polyatomicions: group has a charge due to unequal sharing of electrons among atoms
Exothermic: is a process or a change that releases energy
Condensation: is a change of gas to liquid
Deposition: gas directly to solid
Temperature: is a measure of the hotness and coldness of matter
Subatomicparticles: made of three basic particles called ___________,these are electrons, protons and neutrons
Atomicnumber: the number of protons of an element
Isotopes: are elements have same atomic number but different neutron numbers

Valenceelectrons: are electrons that participates in the formation of a chemical bond
Subshells: Each main energy level in an atom has sub energy levels called _________
Orbitals: are places in the subshell where electrons are most likely to be found
Electronicconfiguration: way of distributing the electrons in their corresponding orbitals
Anion: atom that receives electrons become negatively charged
Cation: atom that give off electrons become positively charged
Oxidation: tendency to become positively or negatively charged
Electronegativity: is the tendency to attract electrons
Affinity: the energy released to add an electron
Ionizationenergy: the amount of energy necessary to remove an electron from atom
Internalenergy: is the total kenetic energy of the particles of matter
Nucleons: Neutrons and protons, collectively are called ________
Massnumber: The total number of protons plus neutrons of an atom
GustavusHinrichs: introduced the spiral periodic system based on atomic weights, spectra and chemical similarities
DmitriMendeleev: was a russian chemist who invented his own periodic table and predict other elements
