alloys over metals because
they react less quick
what do you have to have to start with steel?
iron
molecular compounds do not react as quickly because…
they have a charge
properties most molecular compounds have are…
low melting/boiling points
what is a double bond?
two atoms are sharing two pairs of electrons
what kind of bond does propane have?
