Particulate Nature of Matter

Particles (atoms, molecules or ions), that are in constant motion, have mass and take up space.

Transformation of matter where mass and energy are conserved

The smallest unit of matter. Can be combined to form other substances but cannot be broken down chemically.

A particle of one element. Can be combined in fixed ratios and have different masses than atoms of another element.

Anything that exists but does not have the properties of matter (ex. the ability to do work)

Elementary substance

Chemical compound

Chemical formula

Pure substance

Mixture

Homogenous

Heterogeneous

Numerical data, like temperature or mass, that is measured

Categorical data, like color, that is observed

Change in the appearance or form of the matter

Changes to the kind of matter and at least one new substance with new properties is formed

Separation technique where mixture is poured through a filter

Separation technique where mixture is added to water or organic solvent

Separation technique where mixture is dissolved, cooled and crystals form

Separation technique where a mixture is heated until one or more components vaporize

Separation technique where a mixture is placed on a piece of paper and one end is submerged in water. Components move along the paper
