- Mixture
- A blend of two or more kinds of matter, each of which retains its own identity and properties
- Basic Research
- Carried out for the sake of increasing knowledge, such as how and why a specific reaction occurs and what the properties of a substance are.
- Noble Gases
- Group 18, elements that are generally nonreactive
- Nonmetal
- A element that is a poor conductor of heat and electricity
- Organic Chemistry
- The Study of most carbon-containing compounds
- Atom
- The smallest ynit of an element that maintains the properties of that element
- Gas
- Matter that has neither definite volume nor definite shape.
- Mass
- A measure of the amount of matter
- Technological Development
- Technological Development typically involves the production and use of products that improve our quality of life.
- Solid
- Matter that has definite volume and definite shape
- Pure Substance
- A fixed composition and differs from a mixture in two ways
- Difference between mixture and pure substances 2
- Every sample of a given pure substance has exactly the same composition
- Physical Property
- A characterisitc that can be observed or measured without changing the identity of the substance
- Plasma
- A high-temperature physical state of matter in which atoms lose their electrons
- Liquid
- Matter that has a definite volume but an indefinite shape
- Heterogeneous
- Mixtures that are not uniform in composition
- Volume
- The amount of three dimensional space an object occupies
- Products
- the substances that are formed by the chemical changes

- Mixtures that are uniform in composition
- Matter
- Anything that has a mass and takes up space
- Biochemistry
- The study of substances and processes occurring in living things
- Change of State
- A physical change of a substance from one state to another
- Intensive properties
- Do not depend ont he amount of matter present
- Chemical Property
- Relates to a substance's ability to undergo changes that transform it into different substances
- Metalloids
- An element that has come characteristics of metals and some characteristics of nonmetals
- Theoretical Chemistry
- The use of mathematic and computers to understand the principles behind observed chemical behavior and to design and predict the properties of new compounds.
- Element
- A pure substance made of only one kind of atom
- Extensive Properties
- Depend on the amount of matter that is present
- Periods

- Metal
- An element that is a good conductor of heat and electricity
- Applied Research
- Applied Research is generally carried out to solve a problem
- Difference between mixture and pure substance 1
- Every sample of a given pure substance has exactly the same characteristic
- Inorganic Chemistry
- The study of all substances not classified as organic, mainly those compounds that do not contain carbon
- Chemistry
- The study of the composition, structure, and properties of matter and the changes it undergoes
- Analytical Chemistry
- the identification of the components and composition of materials
- Chemical Reaction
- A change in which one or more substances are converted into different substances
