Element

A material made from only one type of atom

Atom and what it is made of

The smallest unit of matter made up of protons neutrons and electrons

Charges of the different parts of an atom

Protons (+) electrons (-) neutrons are neutral

Compound

A substance formed by the chemical combination of two or more elements

Chemical reaction

The change that happens when one substance reacts to another

Bonds

Forces that hold atoms together

Describe a covalent bond

In a covalent bond, the atoms share electrons and that bonds them together

Describe a ionic bond

One atom gives another atom an electron so that one is positively charged and the other is negatively charged and then they attract to each other

Vander waals forces

The slight attraction that develops between oppositely charged regions of nearby molecules. The molecules need to be within 5 nanometers of each other

What makes a molecule polar

When the charges is the molecule are unevenly distributed

What is a hydrogen bond

Because hydrogen atoms are polar one end of a hydrogen atom can attract to an oppositely charged end of another hydrogen atom. They are not as strong of bonds as covalent or ionic but hydrogen atoms can be in multiple hydrogen bonds at once

What are waters 3 special properties

Adhesion


Cohesion


Heat capacity

What is a mixture

Two substances that are physically mixed together, but not chemically combined

What is a solution and what are the parts

when all the components are evenly distributed. The "dissolving" thing is the solute and the thing that it is dissolving in is the solvent

what is a suspension

a mixture of water and undissolved material

what does the ph scale measure

it measures how acidic or basic something is. In relation to hydrogen ions though, there is more hydrogen ions the lower the number you are at on the ph scale

what will happen if the ph in your body high or too low

It will affect the chemical reactions taking place inside your cells

what are buffers

weak acids or basics that can act against strong acids or basics to prevent sharp changes in ph

what element are all living things based on

carbon

what can carbon do

It can form strong covalent bonds with many other elements

what elements can carbon bond with

Hydrogen


Oxygen


Phosphorous


Sulfur


Nitrogen

What are the 4 macromolecules

Carbohydrates, Proteins, Lipids, Nucleic acids

What are carbohydrates use for

Carbohydrates are used for energy. Sugars are carbohydrates and so are complex carbohydrates. Some plants use Carbohydrates for structural purposes too

What are Lipids used for

Lipids are used to store energy. Examples of lipids are Fats Oils and Waxes. You need Lipids to survive, contrary to popular belief

what are nucleic acids used for

nucleic acids are used to store and transmit hereditary, or genetic, information. Examples of these are DNA and RNA

what are the three jobs of proteins

1) control the rate of reactions and regulate cell processes


2) form important cellular structures


3)transport substances into or out of cells or help to fight disease
