Bonding
4 types of bonds
ionic bonding
how it works
metal gives electrons to non-metal :
opposite ions attract
molecular properties of ionic compounds
high melting points
hard and brittle
dissociate into ions when dissolved in water
solutions and melted compounds conduct but solids do not
metal + nonmetal OR polyatomic ions
polyatomic means:
an molecule with more than 1 atom, that has an overall charge that is not neutral
covalent bonding
How it works
Atoms need full outer shell
they share electrons for the shell
usually 8 in a shell
Molecular properties
electrons closer to the atom with more electronegativity than the other
polar covalent bond
same atom which means same elecronegativity
Nonpolar covalent bond
low melting/boiling points
low enthalpies of fusion and vaporization
soft or brittle solid form
poor electrical and thermal conductivity.
metallic bonding
molecular bonding
weak electrical attraction binds molecules.
