Chapter 7-Ribbing's Chemistry

ionic bond
chemical bond--metals with non-metals
covalent bond
chemical bond--non-metals with non-metals
stable electron configurations
the reason why atoms bond with each other
new compound
the result of the sharing or transferring of electrons between two different types of atoms
ionic compound
molecules that consist of charged ions with opposite charges; usually solids
ion that are electrically charged
positively-charged ion
negatively-charged ion
ionic bonding
transferring of electrons between a metal and a non-metal OR a metal and a polyatomic ion
polyatomic ion
a group of covalently bonded atoms that act as a single ion
ionic substance
composed of a metal and a non-metal or a polyatomic ion (salts)
ionic compound
elements form ions to achieve a stable octet
ionic compound
formed by electrostatic charge
ionic substance
conduct electricity in liquid state, brittle in solid state
ionic compound
always a electrically neutral compound
ionic compound
fixed charge-only one charge to a particular atom
ionic compound
multiple-variable change, transition metals, roman numerals
fixed charge ionic compound
composed of cations and anions
group 1a/2a metals, Al3+, Zn2+, Ca2+, Ag1+, Ammonium ion
group 5a, 6a, and 7a non-metals, polyatomic ions
multiple charge ionic compound
composed of metals that form two or more cations--transition metals (Pb, Sn, Bi)
multiple charge ionic compound
composed of anions
aren't ionic but share properties with ionic compounds
where 8-12 other atoms closely surround each metal atom--METALS
sea of electrons model
all metal atoms in a metallic solid contribute their valence e-'s to form a sea of e-'s
delocalized electrons
valence electrons that are free to move around
metallic bond
the attraction of a metallic cation for delocalized electrons
polyatomic ion
an ion formed by the covalent bonding of atoms of two or more different elements
monatomic ion
an ion consisting of one or more atoms of a single element
oxidation number
the sum of the negative and positive charges on an atom
stable duet
what only H, Li, and Be form
