Chapter 1

study of composition, structure, and properties of matter and the changes it undergoes Chemistry
chemistry of carbon compounds Organic Chemistry
study of compounds that do not contain carbon Inorganic Chemistry
study of the properties and changes of matter and their relation to energy Physical Chemistry
identification of components and composition of materials Analytical Chemistry
chemistry of living things Biochemistry
use of math and computers to understand the principles behind observed chemical behavior Theoretical Chemistry
doing research for the sake of gaining knowledge Basic Research
generally carried out to solve a problem Applied Research
involves the production of products that improve our way of life Technological Development
anything that has mass and volume Matter
measure of the amount of matter Mass
how much space something takes up Volume
smallest unit of and element Atom
pure substance made of only one kind of atom Element
made of 2 or more kinds of atoms chemically bound together Compound
depends upon the amount of matter present Extensive Properties
do not depend on the amount of matter present Intensive Properties
one which you can observe without changing the substance Physical Properties
has a definite shape and volume Solid
has a definite volume but and indefinite shape Liquid
Has neither a definite shape or volume Gas
high temperature physical state of matter in which atoms loses their electrons Plasma
relates to a substances ability to undergo changes that transforms it into different substances Chemical Properties
a blend of 2 or more kinds of matter; each retains its own properties Mixture
solution like saltwater, tea Homogeneous Mixture
not uniform throughout like sand and water, oil and water, wood, blood Heterogeneous Mixture
has a fixed composition Pure Substance
table that organizes all known elements Periodic Table
vertical columns that have similar chemical properties and have the same number of valence electrons Groups or Family
horizontal rows. physical and chemical properties change somewhat regularly across a period and same energy levels Periods
good conductors of heat and electricity solid- many are malleable( pound into different shapes) and ductile (can be drawn out into a wire) most metals have a luster (shiny or a silvery grayish appearance) Metal
not good conductors tend to be brittle gases (mostly) at room temperature Nonmetal
have some characteristics of metals and some of nonmetals solids at room temperature tend to be semiconductors of electricity Metalloids
group 18 and nonreactive and many times are used in lighting Noble Gases
is used to measure liquids Graduated Cylinder
