Chemistry 2.1
formation of ions
ions are charged particles
trying to form a full outer shell
metals form + ions
nonmetals form negative ions
giving away is +
stealing is -
Ionic compounds
structure is called a giant ionic lattice
strong electrostatic force of attraction in all directions
properties of ionic compounds
strong bonds mean high melting point
when solid no conductivity
when liquid can conduct
some dissolve in water
finding the formula
empirical formula
count the atoms of each element
Ionic bonding
transfer of electrons
oppositely charged ions are strongly attracted to each other
dot and cross diagrams
show the arrangement of electrons in an atom or ion
do not show
structure
size
how they are arragnged
