And no that does not mean we are going to bond over a campfire with s'mores... (which quite frankly sounds preferable).
Instead, you, the mystery man/woman, looking at this post can read this blog regarding...
Chemical Bonding
... and bond with yourself.
NUMBA 1: IONIC BONDING
This type of bond occurs between a metal and a non-metal.
The metal (positively charged) will give away some or all of its valence electrons to the non-metal (negatively charged) to create an EPIC neutral ionic compound between two or more atoms.
NUMBA 2: NON-POLAR COVALENT BONDING
Aka COVALENT BONDING will occur between two non-metals (negatively charged) and funnily enough usually between the same non-metals. See what I just did there? You're bonding with yourself by reading this blog and the non-metals are also (often) bonding by themselves. MIND = BLOWN. The two non-metals will come together to share some or all of their valence electrons to create an equally EPIC non-polar covalent compound between two or more atoms.
NUMBA 3: POLAR COVALENT BONDING
This bonding is sooooo similar to "NUMBA 2" but not quite... The only difference is that one side of the covalent bond is getting more of the action. Meaning that the more electronegative / non-metalish atom will still share valence electrons with the less electronegative / non-metalish atom; however the electrons "like" non-metals better (apparently) and will therefore spend more of their time there.
DID YOU KNOW THAT???
A. I just made a Bill Nye - the Science Guy reference.
I. IONIC compounds have a very high melting point cause of their exceedingly mighty bonds
C. COVALENT compounds also have a very high melting point cause of their exceedingly mighty bonds but have a lower melting point because of the weaker bonds that hold multiple covalent compounds together.
Calculating Electronegativity Difference
Elements in the PT (Periodic Table) have specific electronegativities. Not sure what unobtanium's is though, probably because it's un-obtain-able. LOL.
Anywho, to calcuate the ELECTRONEGATIVITY DIFFERENCE (ENeg Diff.) use the simple formula:
Energy difference = Electronegativity 1 - Electronegativity 2.
Which will, ergo, tell you what kind of what kind of chemical bond is formed. Sorry for blowing your mind, again!
SITUATION 1: The ENeg Diif. is less than 0.5 - which means the compound will form a Covalent Bond!
SITUATION 2: The ENeg Diff. is greater than or equal to 0.5 and less than or equal to 1.8 - which means the compound will form a Polar Covalent Bond!
SITUATION 3: The ENeg Diff. is greater than 1.8 - which means the compound will form an Ionic Bond!
"DUUUUUUDE, NARLY, DUUUUDE" - you must be saying.
BAZINGA!
If you're feelin' G and want to learn about bonds watch this vid:
Now, a quick recap on Lewis Diagrams. I know we learned this all last year, but how about a couple examples and diagrams, ok?
This is one of the most common, H2O, but something to notice is that it is bended. Hmmm....

You are probably thinking, "Oh great Chemistry King! How will I know if it is bended or not?"
'Well, young grasshopper, you'll just have to memorize this one." Words of wisdom.
Here's CO2 (yes. "X" is ok too):
Now, if all of that grade ten curriculum isn't coming flooding back to you, check out this video. She makes it look SO simple.
You go gurl. Like a boss.
