Term
energy level
Definition
distance electrons are from the nucleus
Term
orbitals
Definition
paths the electrons follow around the nucleus
Term
valence electrons
Definition
electrons in the highest energy level of the atom
Term
core electrons
Definition
all electrons in the atom except for the valence electrons
Term
Lewis structures
Definition
diagrams showing how many valence electrons an atom has
Term
octet rule
Definition
a rule in which states that when an atom has 8 electrons it is full and stable
Term
molecule
Definition
multiple atoms grouped together and held by molecular bonds
Term
molecular compound
Definition
when molecules have been joined together by a bond
Term
covalent bond
Definition
when a pair of electrons are being shared to join elements
Term
lone pairs
Definition
pairs of electrons in a Lewis Structure that are not being shared
Term
double bond
Definition
when 2 pairs of electrons are being shared between atoms
Term
organic compound
Definition
molecules with an abundance of carbon; commonly known as the molecules of life commonly found in DNA or protein
Term
reactants
Definition
what a chemical reaction occurs to
Term
products

the outcome of a chemical reaction
Term
synthesis reaction
Definition
a type of chemical reaction where there are 2 reactants and 1 product
a+b= ab
Term
decomposition reaction
Definition
a type of chemical reaction where there is 1 reactant and 2 products
ab= a+b
Term
acid base reaction
Definition
when a hydrogen ion is bonded and electrons are lost within a chemical reaction

ah= a(-)+h(+)
Term
condensation reaction
Definition
a chemical reaction where water is produced
Term
chemical reaction
Definition
a process where a substance is altered
Term
polymer
Definition
a molecular structure made up of monomers
Term
monomer
Definition
a single molecule which can be bonded with other molecules to form polymers.
Term
hydrogen ion
Definition
a positively charged hydrogen particle that is positive because an electron was lost through an acid base reaction
