Chemical Bond:
The energy is lower when they are together than when they are alone
Molecule:
A substance made of TWO different OR same elements
Compound:
A substance made of TWO different or more elements
Binary compounds: Just have two elements
Organic compounds: USUALLY contains carbon and hydrogen
Inorganic compounds: USUALLY contains only metals
Chemical/Molecular Formula:
Just the normal H2O kinda formulas
Structural Formula:
Atoms linked together with lines and stuff. (line structure)
Ball and Stick Model:
Like the balls and sticks of bonds and atoms from high school.
Bond Strength AKA Dissociation Energy (D):
The energy required to separate two bonded atoms.
As the bond order increases, so do the dissociation energy, so a double bond is stronger than a single bond.
Bond Length:
The length of the bond, and the shorter they are, the stronger.
This means that the larger radius of the atoms involved the weaker.
Covalent Radius:
How much a specific atom contributes to a covalent bond, so Br is going to contribute more than H.
