Atom smallest piece of matter that has the same properties of the element it is in
proton A positive + subatomic particle in the atoms nucleus. the identity of the element & atomic number
Neutron A neutral subatomic particle in the atom's nucleus....has no charge & most of the mass
electron A negative subatomic particle spinning outside the nucleus of an atom. Tiny!
element The simplest forms of matter that contain only one type of atom
periodic table of elements A chart that organizes all the elements by atomic number & properties
Valence Electron The electron in the outer level of an atom that causes atoms to bond together
Chemical bond An interaction that holds 2 atoms together
Chemical Formula A shorthand way to use chemical symbols and nummbers to represent a substance
Subscript Small number to the right of the element that shows how many atoms there are of an element
Coefficient the large number that multiplies atoms of the element
Chemical Equation Uses symbols to show the relationship between the reactants & the products
Molecule 2 or more atoms joined in a definite ratio
Diatomic Molecule A molecule made of 2 atoms of the same element
law of conservation of mass States that matter is neither created notr destroyed in a chemical reaction
Crystal lattice Repeating 3 dimensional pattern that forms when ions bond
Covalent bond the type of bond that forms when atoms share electrons instead of transferring them
Metallic bond A special bond between metal ions and the electrons that swim around in them
Malleability metals can be pounded into thin sheets
Ductility metals can be stretched into wires
Conductivity metal can conduct electricity and heat
electron dot diagram An easy way to show the valence electrons in an atom or chemical bond
compound A set of elements that are chemically bonded and changed into new substances
Synthesis reaction when two or more substances combine to crete one new compound
Decomposition reaction a reaction where a single compound breaks down to form 2 simpler substances
single-displacement reaction one element replaces another element in compound leaving a new compound and one element
double-displacement reaction the two metal ions in two compounds switch places in a chemical reaction
