a) Matter can be classified in many different ways. One useful way is to classify matter according to its______and ______of particles .
b) Matter is anything that has 1) ______and 2) ______.
c) Matter can be divided into two main categories ______and ______.
d) Pure substances are substances that contain all of the same type of ______. There are two different types of pure substances called ______and ______.
e) Elements are substances that are made up of the same type of particles called ______or called ______molecules where each particle is made up of two of the same atoms bonded together. Elements like gold, tin, lithium and neon are made up of atoms which are individual particles. The majority of elements are like this except for seven elements whose atoms do not remain as individual units and instead form diatomic molecules. These seven elements are called “H, O, Br, F, I , N, Cl”: ______which has the symbol H; ______which has the symbol O; ______which has the symbol Br; ______which has the symbol F; ______which has the symbol I; ______which has the symbol N; and ______which has the symbol Cl.
f) Compounds are substances made up of the same particles called ______which contain two or more DIFFERENT TYPES of ______combined in ______. For example, carbon dioxide is a compound made up of the same type of molecule, represented by CO2. Each CO2 molecule is made up of one ______atom and two ______atoms. Carbon monoxide is a different compound made up of the molecule CO which is composed of one ______atom and ______oxygen atom.
g) Mixtures are substances made up of two or more different ______mixed together. There are two main types of mixtures, ______mixtures and ______mixtures.
h) Homogeneous mixtures are also called ______. They consist of two or more different particles/pure substances which are ______mixed together. This distribution causes a ______appearance that makes the substance look like one ______. Examples of this mixture are: ______which is a homogeneous mixture of gases in the atmosphere; bronze or stainless steel which are both ______made up of a mixture of metals; and sugar water which is made up of a mixture of ______dissolved in water.
i) Heterogeneous mixtures consist of two or more different particles/pure substances ______mixed together. Heterogeneous mixtures can come in two forms depending on how well mixed together they are. The type of heterogeneous mixture that looks like a homogeneous mixture is called a ______. This type of mixture looks like one phase until the different particles settle over time into different visible phases. The denser particles will sink to the bottom and separate from the less dense particles. Two examples of this type of mixture are ______and ______. The other type of heterogeneous mixture is called a ______mixture and is easier to spot because the different particles are so unevenly mixed together that they form visible ______which are easy to distinguish. Two examples of this type of mixture are ______and ______.
