1. Wednesday, October 8 th, 2014 – Day 4 Bio.A.S.1.1: Compare and contrast covalent and hydrogen bonds Objective: All living things are based on atoms and their interactions Warmup: 1.) Draw a picture of an atom. Include any subatomic particles that you remember. 2.) Draw a picture of a water molecule. Label any parts that you remember.

4. The Chemistry of Life

5. Matter is anything that has mass and occupies space

6. All living things are made up of the same kinds of matter as non-living things.

7. Elements and Atoms More that 90 percent of the mass of all kinds of living things is composed of a combination of four elements: oxygen, carbon, hydrogen, and nitrogen.

8. Biology is the study of biological organisms and processes. All biological organisms and processes are created, maintained and changed through chemical processes and are made up of chemical compounds. Without an understanding of chemistry one cannot accurately and fully understand biology.

9. The Atom: It is the smallest unit of all matter. It has three main parts: Proton(+ charge) Neutron (no charge) Electron (- charge) - Protons and electrons are usually equal in number - Elements (substances made of only one type of atom) are identified on the Periodic Table

11. Reading the Periodic Table: How many protons, neutrons and electrons does Carbon contain? Number of protons the atom contains -usually the # of electrons also Number of protons and neutrons inside the nucleus – electrons are too small to affect mass

14. s 8 Bonding, the way atoms are attracted to each other to form molecules, determines nearly all of the chemical properties we see. And, as we shall see, the number “8” is very important to chemical bonding.

15. Molecule – Two or more atoms held together by a chemical bond. Forms when atoms are combined. a. Covalent bond – Chemical bond formed when atoms share electrons.

16. Ionic bond - Chemical bond where electrons are given away or received. a. Held together by opposite charges b. One atom takes electrons from another atom SODIUM CHLORINE

A proton has a charge, and it is found. 2.) A neutron has a charge, and it is found. 3.) An electron has a charge, and it is found.
