-a type of atom

- refer to the periodic table

What is an Ion?

How does one become an Ion?

-a charged particle

 -it loses an electron

What is an Isotope?

How does it become an isotope?

-Atoms that have the same number of protons but different number of neutrons

-Same atomic number but differ in their mass number

-It gains a Neutron

Carbon-12: 6P, 6N, 6E

Carbon-13: 6P, 7N, 6E

Carbon-14: 6P, 8N, 6E

Atomic Number

&

Atomic Mass

Atomic #: is the number of protons

Atomic Mass: is the weight of both the proton and neutrons.

-negative charge

-on the orbitals

energy level 1: 2

energy level 2: 8

Covalent: shared electrons

Ionic: giving away of electrons

-made up of atoms

-grouped together by energy

refer to the periodic table

examples: hydrogen, carbon, sodium

What are the properties of water?

4 and explanations

Heat storage: require a high amt of heat before they break, minimizing temperature changes

Ice Formation: ice crystals are spaced far apart because of hydrogen bonding

Vaporization: Hydrogen bonds much be broken in order for it to turn into air

Cohesion: bonds hold melecules of water together, forms a dome before it spills over

Adhesion: has the capacity to stick to objects, water travels up thetowel when placed in water

High polarity: H2O molecules are attracted to ions and polar compounds

the -log[H+]

- the acid level or the basic levels of a substance

What is the range of the pH scale?

What is acidic and what is basic?

0-14

acidic: 0

basic: 14

neutral: 7

- substance the takes up or releases hydrogen ions into solution as the hydrogen io concentration of the solution changes.

Lipids:unsaturated & saturated

Proteins:

Carbohydrates: 

Nucleic Acids:
