Energy, Elements & Compounds, Periodic Table of Elements

Made of a blend of elements and compounds; is not a pure substance because it does not have consistent properties

The solid Earth, is made of a limited number of elements and is primarily composed of oxygen and silicon

The transfer of energy by the movement of electromagnetic waves or subatomic particles.

New substance formed from a chemical change, resulting in solid particles that form or separate out of a liquid

Energy can neither be created nor destroyed; energy just changes form.

A material that does NOT conduct heat or electrical current is an insulator.

Distinct forms of matter known in everyday experience: solid, liquid, and gas; also referred to as phases.

Matter is anything that has mass and takes up space.  Matter occurs as elements, compounds, and mixtures.

The sum of all living matter; mad of a limited number of elements including O, C, H, N, Ca, and P.

Properties are the physical and chemical characteristics of matter used to describe or identify a substance.

A measure of how much matter is present in a substance is ________.

Production of gas, Color change, Production of heat/light, Temperature change, Production of precipitate are evidence of

Sort or group together based on shared characteristics, physical properties, or chemical properties

A substance that readily transfers heat or electrical energy is known as a conductor.

Glass shatters easily. This is an example of which physical property?

A physical property; able to be shaped or formed into thin sheets by hammering or pressure (aluminum foil).

A circular movement of fluids caused by the rising of hotter, less dense fluid & the falling of cooler, more dense fluid

Any form of matter that is uniform throughout and has consistent properties.

Made of the same evenly distributed substance or combination of substances throughout

A change to a substance that occurs without forming a new substance,  such as a change in size or state of matter.

The acronym MRS CHE represents six forms of ________.

Elements that are not shiny, not malleable, & poor conductors of heat & electricity; usually gases or brittle solids.

Elements that have properties of both metals and nonmetals; sometimes referred to as semiconductors

A physical property; the way the surface of a substance shines or reflects light; shiny, dull, glassy

The layer of gas around planet Earth; held in place by gravity & composed of a limited number of elements, N and O.

Heat transfer caused by the rising of hotter, less dense fluids and the falling of cooler, more dense fluids.

The change of energy from one form to another.

Milk that has expired forms solid pieces, which is an example of the formation of a ________ ?

Thermal energy is the total kinetic (motion) energy of tiny particles that make up matter.

Most elements; they are typically solid, shiny, malleable, and good conductors of heat and electricity

Transfer of thermal energy that occurs in solids, liquids, and gases when two substances of different temperatures touch

Change that alters the identity of a substance resulting in a new substance & different properties is a ________.

All water on Earth: oceans, surface water, ground water, and glaciers; made of a limited number of elements (O, H).
