Ionic Bonds
the type of elements involved (_______ + _______)
Metal + Nonmetal
the type of elements involved (_______ + _______)
nonmetal + nonmetal
makes up 80% of the periodic table
metals
forces/attractions that exist between molecules
intermolecular forces/attractions
metallic bond
positively charged ion (usually a metal)
cation
covalent compounds are also known as
molecular compounds
halogens are a special type of
nonmetals
a weak intermolecular force between nonmetals
London dispersion forces
another word for outermost; used to describe outermost electrons and orbitals/shells
valence
negatively charged ion (usually a nonmetal)
anion
contain exactly two atoms that are chemically bonded
diatomic molecule
elements of this broad classification are used in making computer chips
metalloids
the three states of matter
solid, liquid, gas
the tendency of atoms to prefer to have eight electrons in the valence shell
octet rule
electrons are ________ between elements in an ionic bond
transferred; stolen; given away; taken in (all acceptable answers)
electrons are _________ between elements in covalent bonds
shared
the number of valence electrons that family 1A would have
1 electron
attractive forces between the positive end of one polar molecule and the negative end of another polar molecule
dipole-dipole forces/interactions
a way to describe how electrons interact in a metallic bond
sea of electrons or delocalized electrons
if element A steals an electron from another element in an ionic bond, what happens to element A
becomes negative; becomes an anion
an ion composed of two or more atoms; also known as a molecular ion, is a covalently bonded set of two or more atoms, or of a metal complex, that can be considered to behave as a single unit and that has a net charge that is not zero
polyatomic ion
the number of valence electrons that halogens have
7 electrons
a very strong intermolecular force where the smallest element is attracted to an atom of another molecule
hydrogen bond
the unequal sharing of electrons, often creating a dipole moment
polarity
