Bonding and Reactions

	the combining of atoms to form molecules or ionic compounds
	the force that holds two atoms together.
	the number of protons in the nucleus of an atom
	electrons on the outermost energy level of an atom
	a chemical bond in which one atom loses an electron to form a positive ion and the other atom gains an electron to form a negative ion
	electrically charged atoms that have gained or lost electrons.
	the regular pattern in which a crystal is arranged
	a chemical bond that involves sharing a pair of electrons between atoms in a molecule
	two or more atoms held together by covalent bonds
	a molecule consisting of two atoms
	a bond formed by the attraction between positively charged metal ions and the electrons around them
	the ability of a substance to be pulled into a wire
	the ability of a substance to be hammered or beaten into thin sheets
	the process by which one or more substances change to produce one or more different substances
	A solid that forms and settles out of a liquid mixture
	a chemical reaction in which heat is released to the surroundings
	A reaction in which energy is absorbed
	the law that states that energy cannot be created or destroyed but can be changed from one form to another
	a combination of chemical symbols and numbers to represent a substance
	a small letter or number written below and to the right of a chemical symbol
	a representation of a chemical reaction that uses symbols to show the relationship between the reactants and the products
	the starting materials in a chemical reaction
	the substances that are formed by the chemical change
	the law that states that mass cannot be created or destroyed in ordinary chemical and physical changes
	A number in front of a chemical formula in an equation that indicates how many molecules or atoms of each reactant and product are involved in a reaction.
