Composition of Atmosphere, Oceans & Living Organisms A Reynolds’ Production 2010
Review Really Fast 1.All elements are pure substances because it has one type of atom and cannot be broken down. 2.All compounds are made up of 2 or more elements chemically joined together to form a new substance. 3.All elements have chemical symbols that start with a capital letter… **** HINT****
Review Really Fast 1.Oxygen is most common in Earth’s Crust 2.Silicon is second common in Earth’s Crust 3.Together, Oxygen & Silicon make up 75% of the Earth’s Crust… 4.All other elements are in small amounts….
Limited Number of Elements There were a limited # of elements that make up Earth’s Crust…. The same is true for the Atmosphere, Oceans, & Living Organisms
Title your Journal Page Elements of Atmosphere, Oceans, & Organisms 19

Oceans/Seawater Elemental composition of Earth's ocean water (by mass) Element Percent Element Percent Oxygen 85.84 Hydrogen 10.82 Chlorine 1.94 Sodium 1.08 Magnesium 0.1292 Sulfur 0.091 Calcium 0.04 Potassium 0.04 Bromine 0.0067 Carbon 0.0028
Look at the Periodic Table for Ocean I wonder if the Krabby Patties are made out of these elements????
The elements that in animals include: 1.oxygen (65%) 2.carbon (18%) 3.hydrogen (10%) 4.nitrogen (3%) 5.calcium (1.5%) 6.phosporus (1.2%) 7.potassium (0.2%) 8.chlorine (0.2%) 9.sulfur (0.2%) 10.sodium (0.1%) 11.magnesium (0.1%) 12.iron (0.1%) 13.copper (0.1%) 14.iodine (0.1%)

The elements that in plants include: a few elements (C,H,O, N, S, P, Cl, F, Br, and I) make up practically all... Plants and soil organisms cannot take up most organic molecules until they are
V. Animals MOSTLY need Oxygen to survive VI. Plants need Nitrogen, Carbon, Oxygen, and Hydrogen to survive. a. Plants need Nitrogen to survive b. Carbon and Oxygen make carbon dioxide c. Hydrogen and Oxygen make water Limited # of elements % Oxygen65 Carbon18 Hydrogen10 Nitrogen3 Calcium1.5 Other~1
TABLE 1. The Essential Elements, Their Form for Uptake, and Functions in the Plant Essential ElementForm for UptakeFunctions in the Plant C, H, O, N, SIons in solution (HCO 3 -, NO 3 -, NH 4 +, SO 4 2- ) (O 2. N 2, SO 2 ) Major constituents of organic material; essential elements of, or gases in, the atmosphere atomic groups involved in enzymatic processes; assimilation by oxidation- reduction reactions P, BIons in solution (PO 4 3-. SO 4 2- )Esterification with native alcohol groups; the phosphate esters are involved in energy transfer reactions K, Mg, Ca, ClIons in solution (K +. Mg 2+, Ca 2+, Cl - )Nonspecific functions establishing osmotic potentials; more specific reactions in which the ion brings about optimum conformation of an enzyme protein (enzyme activation); bridging of the reaction partners; balancing anions; controlling membrane permeability and electropotentials
