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.

The Chemistry

of Life

Matter is anything that has mass and occupies space

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

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.

I. WHY IS IT IMPORTANT TO STUDY CHEMISTRY IN BIOLOGY?

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.

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

Reading the Periodic Table:

How many protons, neutrons and electrons does Carbon contain?

Number of protonsthe atom contains

-usually the # of electrons also

Number of protonsand neutrons inside the nucleus – electronsare too small to affectmass

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.

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.

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
