Unit 4A - Atoms, Elements, and Carbon

What is carbon?

• An chemical element that can be found in all living things.

• A type of metal used in construction.

• A synthetic compound used in plastics.

• A gas that is only found in the atmosphere.

Where can carbon be found?

• It's found in all living things. Found in many rocks, oceans, the atmosphere, in living things.

• Only in the atmosphere.

• Only in the oceans.

• Only in rocks.

How does carbon move?

• Carbon moves between reservoirs (connected to the spheres of the earth) by processes.

• Carbon remains static in the atmosphere.

• Carbon only moves through human intervention.

• Carbon is only found in the ocean.

Where is Carbon stored?

• A carbon reservoir is a place where carbon is stored.

• In the atmosphere

• In the ocean

• In fossil fuels

What is an element?

• A pure substance made of only one kind of atom.

• A mixture of different compounds.

• A substance that can be broken down into simpler substances.

• A combination of two or more different elements.

What is an atom?

• Basic unit of matter.

• A type of molecule.

• A form of energy.

• A chemical reaction.

What is a compound?

• Two or more elements chemically joined together (i.e. elements aren't just mixed).

• A single element in its pure form.

• A mixture of elements that are not chemically bonded.

• A solution of a single element in water.

What is a molecule?

• Two or more atoms chemically joined together.

• A single atom by itself.

• A mixture of different substances.

• A type of chemical reaction.

What is a proton?

• A positively charged particle found in the nucleus of an atom.

• A negatively charged particle found in the nucleus of an atom.

• A neutral particle found in the nucleus of an atom.

• A positively charged particle found outside the nucleus of an atom.

What is a neutron?

• A small particle in the nucleus of the atom, with no electrical charge.

• A positively charged particle in the nucleus of the atom.

• A negatively charged particle orbiting the nucleus of the atom.

• A particle responsible for the chemical properties of an atom.
