Atom vs molecule
one piece vs multiple together

letters are the element number is how many atoms
What happens in an ionic bond
one atom strips away the electron og the other aton
Which atoms form ionic bonds

How to predict if an atom will give share or take their electrons
where they are on the periodic
Chemical bond
when ions or atoms come together to create a molecular bond
HONC rule

Single double and triple bond
different bonds that atoms need
covalent
sharing electrons
polar covalent
sharing but one pulls stronger
ionic
one strips away the electron
4 layers of the atmosphere

where are most of the particles located
troposphere
how do pressure and temperature change
pressure drops as you go higher and so does temperature
Where do the phenomena in #11 occur
