4 Calculating Subatomic Particles (continued) If the number of protons changes the result is a new element If the number of neutrons changes the result is an isotope If the number of electrons changes the result is an ion Ion atom with a charge because it gains or loses electron(s) Ions are written as exponents to the symbol (Ca +2, F - ) When electrons are gained, the charge is negative (F - gained 1 electron) When electrons are lost, the charge is positive (Ca +2 lost 2 electrons) Element Mass Rounded to the nearest whole number Protons Neutrons Electrons Atomic # Ca = O = C = Ti = Elements Essential for Life Oxygen Hydrogen Nitrogen Carbon Phosphorus Sulfur Elements Important for Most Life Calcium Sodium Magnesium Potassium Chlorine Trace Elements V Cr Mn Fe Co Cu Zn Mo Cd Sn I B A Si Se F

5 Elements Related to Biology Oxygen (65% of human mass) Found mostly in water (60%) Found in all macromolecules Used in reactions to make energy Can oxidize cells in the body by pulling off electrons (dead cells) Carbon (18% of body mass) Found in all organic cells Can form long chains and large rings Can form up to 4 bonds with other elements Hydrogen (10% of body mass) Found mostly in H 2 O Found in most organic molecules Acts as a proton donor Nitrogen (3% of body mass) Found mostly in the atmosphere as N 2 Humans get nitrogen from food, not the air Necessary for DNA, RNA, and proteins Phosphorus (1% of body mass) Found mostly in bones and teeth Found in DNA Sulfur (.25% of body mass) Found mostly in amino acids which are part of proteins Calcium (1.3% of body mass) Found in bones and teeth Involved in muscle contractions If deficient, the body will pull it from bones and teeth (osteoporosis) Sodium/Potassium Necessary for electrochemistry Regulates involuntary muscle movements Chlorine Found in hydrochloric acid (HCl) in the stomach Necessary for the enzyme in reactions where energy is made

6 Elements Related to Biology (continued) Magnesium Found in teeth and bones Controls enzyme reactions Vocabulary Compound two or more atoms bonded together Does not have the same properties as the atoms Chemical bond - attractive force between atoms Ionic bond forms between metals and nonmetals Forms when electrons are moved causing an atom to have a charge Negative charges bind with positive charges Goal is to have a neutral charge (oxidation numbers add up to zero) Covalent bond Forms between two nonmetals Forms when atoms share electrons Allows for a wider variety of molecules than ionic bonding 10/6/17 Vocabulary Quiz Matter - substance that has mass and takes up space Mass - the amount of matter in a given space Weight = mass x gravity Element - a substance that cannot be broken down by chemical means Atom - building block of all matter Nucleus - positively charged central part of an atom, contains protons and neutrons Proton - found in the nucleus (+ charge) Neutrons found in the nucleus (no charge) Electrons not in the nucleus (- charge) Atomic number whole number on the periodic table, # of protons and # of electrons Atomic mass number on the periodic table that has decimal places, # of neutrons + # of protons Isotope form of a chemical element with the same atomic number but different numbers of neutrons

7 Compound - two or more atoms bonded together Chemical bond - attractive force between atoms Energy ability to do work Chemical reaction rearrangement of atoms to form new compounds Reactant/reagent the original elements or compounds involved in a chemical reaction Product the result of a chemical reaction Metabolism - total of all chemical reactions in your body 10/9/17 Chemical Reactions Molecule simplest form of a substance that retains the properties of that substance Chemical reactions rearranging of atoms to form new compounds Chemical Reactions (continued) mass, quantity and identity of the atoms on one side are identical to the other side 2H 2 + O 2 2H 2 O Activation energy - For a reaction to happen, it has to have enough energy Chemical Reactions (continued)

8 Some reactions have a certain need for the reaction to occur (written above the yield symbol) 10/10/17 Redox Reactions reaction where electrons are moved around and ionic bonds are formed Reduction/Oxidation when one happens so does the other Reducing agent element that loses electrons in a redox reaction and gets a (+) charge Oxidizing agent element that gains electrons in a redox reaction and gets a (-) charge Lewis model looks at the outer shell Outer layers are stable when their outer shell is full Solutions Solutions mixture where one substance is dissolved by another Soluble can be dissolved Insoluble cannot be dissolved Solutions have two parts Solvent substance that does the dissolving Solute Substance being dissolved Solution = solvent + solute Solvents pull particles off of solutes to dissolve them

9 Solutions (continued) Aqueous Solution solution where the water is the solvent Cells are in an aqueous environment 10/11/17 Concentration amount of solute dissolved in a certain amount of solvent 3g/ml 3 grams solute in 1 ml of water Concentrated solution a large amount of solute in solvent Dilute solution a small amount of solute in solution Water often referred to as the universal solvent, but not everything dissolves in water Saturation Point point at which a solution cannot dissolve any more solute To raise saturation point: Vocabulary Quiz Add more solvent Increase temperature catalyst speeds up a chemical reaction by reducing the amount of activation energy necessary to start a chemical reaction redox reaction oxidizing agent gains an electron reducing agent loses an electron solution solvent solute soluble insoluble concentration saturated solution aqueous solution

10 10/16/17 Water H 2 O 4 major properties make it important in biology: Polarity Hydrogen bonding (weak bond) Density Temperature regulation Polarity Polar - the distribution of electrons between covalently bonded atoms is not even Most properties of water come from the formula and shape Electrons are not shared evenly Oxygen uses them more There is a partial charge to both ends of the molecule Oxygen partial negative (-) Hydrogen partial positive (+) Water is still neutral Hydrogen bond weak bond between hydrogen with a partial positive charge and another atom with a partial negative charge. Cohesion - attraction of molecules for other molecules of the same kind Adhesion - attraction of molecules for other molecules of a different kind

11 10/18/17 ph measure of how acidic or basic a substance is measure of the amounts of H 3 O + and OH - Acids have more hydronium (H ) ions Low ph Fruit juices, sodas, ketchup, coffee Bases have more hydroxide (OH - ) ions High ph Alka-Seltzer, Windex, baking soda, bleach ph scale range of possible phs < 7 is acidic > 7 is basic Each number is 10x more/less acidic or base than the adjacent number Buffer Solution solution that resists change In ph Helps to maintain homeostasis Unit Test Friday 10/27/17 TEST***TEST***TEST*** TEST***TEST***TEST*** TEST***TEST***TEST*** TEST***TEST***TEST***TEST
