Atoms
particle of an atom with no charge
neutron
center of the atom
nucleus
First element on periodic table
interaction that holds atoms or ions together
chemical bonding
particle made up of 2 or more atoms
molecule
positively charged particle of an atom
proton

protons and neutrons
this separates the metals from nonmetals
zigzag line
electrons on outermost energy level
valance electrons
type of bond that has properties of low solubility, low melting point and is a poor conductor
covalent bonds
Smallest particle that an element can be divided into and still be the same element
Atom
Number of protons in the atom
atomic number

metalliods
particle that has charge
ion
Bond that has electrons that are "freely" moving
metallic bond
electron

names of the rows and columns on the periodic table
groups and periods
bond forming when atoms gain or lose and electron
ionic bonding
able to be pounded into sheets is called
