To know
Valence electron
Outer most electrons on the last shell
Anion
Ion that accepts an electron and will have a negative charged
Cation
An Ion that gives an electron and will have a positive charge
Covalent bond
What does it look like for a structural diagram?
What does it look like for a molecular diagram?
Sharing of electrons
H-H
H₂
Double Bond
A chemical bond in which two pairs of electrons are shared between two atoms
O₂
O=O
Molecule
Formed when two or more atoms are linked together by covalent bonds
Polar covalent bonds
Chemical bond where a pair of electrons are unequally shared between two atoms. An example of this is a water molecule
+H O-
+H
Elctronegativity
Is the measure of The tendency of an atom to attract a bonding pair of electrons towards itself
Chemical reaction
Means bonds are being broken ( other than hydrogen bonds)
Domain
Is a group of organisms that is the highest of its kind
Polarity
Causes hydrogen atom to be attracted to the oxygen atoms in other water molecules
Hydrophilic
Substances that dissolve in water and like water
Hydrophobic
Things that don’t dissolve in water or don’t like it
Solvent
A substance that dissolves things
Solute
The things being dissolved in a solvent
Hydroxyl
An entity with the formula OH it is an alcohol
Calorie
The amount of energy it takes to raise one g of water 1 degree Celsius.
Ex. It take 540 calories to vaporize 1 g of water
