Atom Bonding: Atoms want to be “HAPPY” AS I HAVE STATED! The idea behind this isAtomic shells want to be full. Some atoms have too many electrons and some wantto give up atoms.

EX: Sodium Magnesium11 total electrons 12 total electrons2 filled shells 2 filled shells1 extra electron 2 extra electrons

REMEMBER: Atoms want to have a full shell; to be HAPPY.

Sodium and Magnesium have a couple of extra electrons. The way chemistryworks is, it is easier to give up extra electrons. There are atoms that want extra electrons. Look at Oxygen and Fluorine:Oxygen: Fluorine:8 total electrons 9 total electrons1 full shell 1 full shellTo be happy it wants 2 more 1 missing electron# Think about water = H2OEach want a full shell of eight:

They can share and make a Covalent Bond or make an Ionic Bond. Now forAn example:

Sodium has an extra electron; Fluorine wants one!!!! So Sodium gives one to Fluorine and then “EVERYONE IS HAPPY”

IONS: A normal atom is called neutral. This is when an atom has a number ofelectrons that is equal to it’s atomic number.

Example: A Sodium atom equals 11 electrons it has 1 too many, so it finds an atom that needs one; so it can give it up to. Clorine can take the extra electron from Sodium “YOUR HAPPY” You’re an Ion – missing an electron You’re a Sodium ion Now you have 10 electrons; but Neon has 10 electrons YOU ARE NOT NEON!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! You’ve become an ion Your not attractive electrically , but other charged ions see you as a good partner!!!! A lot like dating!

You need to remember Atoms can share an electron or they can give upAn electron.

COVALENT: MEANS SHARE ELECTRONS

IONIC : MEANS ELECTRONS ARE GIVEN UP!
