All atoms have the same number of atoms.
Elements
5
Composed of two or more elements chemically bonded in a definit fixed ratio by mass.
Compound
6
A type of matter composed of varying proportions of two or more substances that are just physically mixed, not chemically bonded.
Mixture
7
A mixture that is uniform throughout which like it might be just one substance.
Homogeneous
8
A mixture that has at least two or more components can be observed.
Heterogeneous
9
All elements are made up od atoms.
Atomic Theory
10
An element having the same atomic number but different mass number.
Isotopes
11
An atom or geoup of atoms with one or more positive or negative electrical charges.
Ion
12
Second building block of some types of matter.
Ion
13
Contains at least two carbon atoms combined with atoms of other elements.
Organic Compounds
14
A compound carbon of few number of carbon atoms are present.
Inorganic compounds
15
Compounds of hydrogen and carbon atoms. Ex: CH4 simplest natural gas, octane: component of gasoline
Hydrocarbons
16
Compounds of carbon, hydrogen and chlorine atoms. Ex: insecticide DDT(C14H19C15)
Chlorinated Hydrocarbons
17
Carbon, hydrogen and oxygen. Ex: glucose
Simple Hydrocarbons
18
Cellulose and starch, which consist of 2 or more monomers of simple sugars such as glucose.
Complex carbohydrates
19
Formed by monomers called amino acids.
Proteins
20
Smallest and fundamental structural and functional units of life.smallest and fundamental structural and functional units of life.
Cell
21
Basic unit of inheritance found in the DNA molecules that contain genetic information.
Genes
22
Special DNA molecule together w/ proteins.
Chromosome
23
Measure of how useful a given sample of matter is as a resource for humans.
Matter Quality
24
Highly concentrated, typically found near the earth's surface, and has great potential for use as a resource
High Quality Matter
25
Not highly concentrated, often located deep underground or dispersed in the ocean or atmosphere, and usually has little potential for use as a resource.
Low Quality Matter
26
Thare is no change in its chemical composition.
Physical Change
27
There is a change in chemical composition of the substance involved.
Chemical Change
28
Changes in the nuclei of its atoms(radioactive decay, nuclear fission, nuclear fusion)
Nuclear Changes
29
A measure of an energy source's capacity to do useful work.
Energy Quality
30
Concentrated and has a high capacity to do useful work. Examples are very high-temperature heat, nuclear fission concentrated sunlight, high-velocity wind, and energy released by burning natural gas. gasoline, or coal.
High-Quality Energy
31
Dispersed and has little capacity to do useful work. An example is heat dispersed in the moving molecules ofa large amount of matter (such as the atmosphere or an ocean) so that its temperature is low.
Low-Quality Energy
