Radioactive Dating and CHONPS Paragraphs 

describe the premises of radioactive dating 

1. [c14] in the environment is constant

2. living things assimilate c14 from foods.

3. [c14] in an organism equals the amount of [c14] in the environment.

4. [c14] in dead organisms decrease due to the. c14 decaying radioactively

5. The age of organic material can be determined by comparing the consent ration of c14 in dead organism to the consent ration of c14 of living organisms knowing that the half-live of c14 is 5800 years

CHONPS Paragraph

1. CHONPS are all small atoms
2. They have few electrons: their electrons have low energy, and they are tightly bonded to the nucleus. These low energy electrons form stronger covalent bonds.
3. Carbón forms 4 bonds in a tetrahedral, space filling configuration. This distributes the electron clouds equally in three dimensional space and results in carbon forming the strongest, and most stable covalent bonds.
4. All but hydrogen are capable of making multiple covalent bonds. Each make a different number of bonds: O-2, N3, C-4.
5. the variability of bond capacities and multiple covalent bonds increase the diversity of potential organic molecule constructs.
