Definition
2 electrons max
8 electrons max
8 electrons max
when the valence shell is maxed out it is named "noble" or snooty. doesnt interact with others |

Term
|
Definition
a group of atoms bonded together
possibly from either; covalent bonds or ionic bonds.
|
|
|
Term
|
Definition
| atoms or molocules with an electrical charge resulting from the loss or gain of electrons |
|
|
Term
|
Definition
When the two molocules share electrons.
Each atom contributes atleast one member of the pair.
Very strong/hard to break
single, double and triple electron pairs |
|
|
Term
|
Definition
| How much an atom wants an electron, further right on the table the more an electron wants it. |
|
|
Term
|
Definition
| The attractive force a nucleus has on an atomic Nucleus exerts on electrons |
|
|
Term
|
Definition
Partial negative charge on a molocule and the partial positive of the hydrogen end of another molocule forms to make a hydrogen bond
forms between water molocules |
|
|
Term
heat capacity in water molocules is due to
|
|
Definition
| the many hydrogen bonds in water |
|
|
Term
1. Hydrophilic
2. Hydrophobic
|
|
Definition
1. loves water, will be surrounded by water molocules
2. hates water, will stick in a clump of molocules |
|

Term
|
Definition
change in genetic makeup of a biological population through time
Bird ex: predators eat alot of white birds, the black birds fly/survive |
|
|
Term
|
Definition
1. When like molocule bond together
2. When unlike molocules bond together |
|
|
Term
|
Definition
when one atom or molocule really wants to take an electron and one atom or molocule really wants to give it away.
Na has 1 electron in its outer shell and Cl has 7. Na gives its electron to Cl. Na then becomes slightly positive and Cl slightly negative. opposites attract and we have an ionic bond. |

Definition
1. Composed of a common set of chemical structures and similar components
2. Contains genetic information that uses a nearly universal genetic code
3. Extract energy from the environment and use it to do biological work
4.Regulate their internal environment
5. Replicate their genetic information in the same manner when reproducing
6. Share sequence similarities between fundamental set of genes
7. Evolve through gradual changes in genetic information
