exam 2 4.2
defin covalent bond
to atons share pares of valence electrons (mostly metals and nonmetals)
scetch covalent bond energy
start above line then go bellow then get closser toline
what is a metalic bond
metal sea of electrons surounding metal atoms
define bond length
averge distance between 2 nucleus of bonde atoms
what is bond energy
the minimum energy required to seperate a chemical bond
defin electonegativity
the attraction of an atom for bonding electrons
electronegativity
increas toward He
what is apure nonpolar covalent bond
Electrons shared =ly
what is a polar covalent bond bond
electrons shared unequally
Ionic bond
Electrons transferred not sharing at all
what will this electron difference make(0-.5)
nonpolar covalent
what will this electron difference make (.5-2.)
polar covalent
what will this electron difference make (2+)
ionic
when will atoms have a bond dipole moment
will be polar if carges dont cancele each other out
how draw dipole moment
arow to negative charge
