*a material in which all of the basic particles are identical
* physical properties include hardness,melting point,and density 
* Chemical properties include reactivity and flammability
* major categories or elements; Metals,nonmetals and metalloids
* Metals conduct heat or electric current well
*Nonmetals do not conduct heat and electric current very well
*Metalloids have some of the properties of metal and some of the   properties of nonmetals

chemical change,or reaction,happens when one or more substance are changed into one or more other substance
*properties of  compound can be very different from those of its elements
chemical reactions,two or more elements combined to form a compound
*Chemical properties include changes that occur when compounds are exposed to other chemicals or heat or light
properties of a compound differ,not only from those of other compounds,but also from those of its elements
*some compounds can be broken down into their elements by applying heat or using electricity
*Every compound has a unique set of properties

*Chemicals can form mixtures
*No chemical change happens when a mixture is made
a mixture is a physical change
solution is a homogeneous mixture
*The component that is present in the largest amount is called the solvent
*Substances present in smaller amounts are called solutes
*A measure of the amount of solute in a given amount of solvent is concentration
*Solubility refers to the ability of a solute to dissolve in solvent at a certain temperature
