So COVALENT means SHARING VALENCE ELECTRONS. In other words when 2 Atoms Share A VALENCE ELECTRON THEY COVALENTLY BOND!
COVALENT
CO- Signifies SHARING
-VALENT refers to VALENCE electrons
MAKES SENCE RIGHT?
BONDS
AND MOLECULES
WELL ITS BASICALLY TO FORFILL THEY'RE DESTINY!! ALL ATOMS WANT TO HAVE A FULL OUTER SHELL... SO WHAT DO THEY DO TO GET IT? IF A ATOM WITH 7 VALENCE ELECTRONS IS LOOKING TO UBTAIN ITS 8TH VALENCE ELECTRON, IT JUST HOLDS ON TO THE UNPAIRED VALENCE ELECTRON OF ANOTHER ATOM WITH 7 VALENCE EECTRONS! TO MAKE IT EASIER FOR YOU GUYS, TAKE A LOOK AT THAT PICTURE!!! IT'S A PICTURE OR AN OUTER SHELL OF A ATOM WITH 7 VALENCE ELECTRONS! THEY ARE BOTH COVALENTLY BONDING!!!
THE THREE TIPES OF BONDS WITH AN EXAMPLE FOR EACH!!
SO WAIT WHY DO ATOMS SHARE ?
THIS BRINGS US TO WHAT ARE MOLECULES? ITS SIMPLE MOLECULES ARE ANY GROUP OF ATOMS HELD TOGETHER BYBY COVALENT BONDS!!
A SIMPLE VIDEO WHICH EXPLAINS HOW TO DRAW DIAGRAMS OF MOLECULES THAT SHOW THE TYPES OF BONDS INVOLVED!
TEST YOURSELF!: 1. WHY DO ATOMS SHARE VALENCE ELECTRONS? 2.WHAT ARE MOLECULES? 3. DRAW A DIAGRAM OF THE MOLECULE F2.(FLURINE) 4.NAME ALL THREE TIPES OF COVALENT BONDS. 5.WHAT IS THE NAME OF N2O 6.FIND OUT THE NAME AND CALCULATE THE FORMULA FOR CARBON DIOXIDE!!
HOW TO DETERMIN NAMES FOR MOLECULES FROM THE FORMULAS?: ITS REALLY QUITE EASY. LETS TAKE NaCl FOR EXAMPLE. Na = Sodium Cl= Chlorine TO CREAT THE NAME YOU MUSST ALWAYS ADD -IDE TO THE END OF THE SECONDLAST ELEMENT AND THE NAME OF THE FIRST ELEMENT MUST REMAIN THE SAME! IT REALLY SIMPLE!! SO IN THIS CASE: SODIUM+CHLORINE = SODIUM CHLORIDE DETERMINING THE FORMULAS FOR THE MOLECULES FROM THE NAMES IS EVEN EASIER! ALL YOU NEED TO DO IS TO REVERS THE WHOLE CONCCEPT!! FOR EXAMPLE IF WE ARE GIVEN HIDROGEN OXIDE. WE SIMPLY KNOW THAT THE THE TWO ELEMENTS ARE HIDROGEN=H AND OXIGEN=O WHICH EQUALS H0!!! NOW TO DETERMIN THE AMOUNT OF EACH MOLECULE, ONE MUST CALCULATE THE AMOUNT OF VALENCE ELECTRON EACH ELEMENT NEEDS AND BY FINDING OUT WHICH OF THE ELEMENTS NEED HOW MANY VAALENCE ELECTRONS TO FILL ITS SHELL, YOU CAN FIND OUT HOW MUCH OF EACH ELEMNT TO CREAT THE MOLECULE. You must also ad the before each of the words: Di-2 is there are 2 of this atoms in the molecule or... Tri-3 Tetra-4 Penta-5 Hexa-6 etc...
PLAY MUSIC!
merry christmas!
