What is Matter?
Anything that has a mass and occupies a space.
100
How are elements arranged on the periodic table?
In order of increasing atomic number (number of protons) and increasing atomic mass.
100
What are two properties of ionic compounds?
High melting and boiling points, Solids at room temperature, made with a metal and a non-metal, Good conductors of electricity, Distinct crystal shape
100
What is a chemical reaction?
When two or more substances combine to produce new substances.
100
What is the name given to the change of state from a liquid to a gas?
Evaporation
200
What is the name given to the change of state from a gas to a solid?
Deposition.

What (2 items) does the atomic number of an element tell us?
It tells us the number of protons in one atom of the element. It also tells you the number of electrons before the atom has bonded to anything. (Since the mass of one proton=1 amu, this is also the mass of protons in one atom of the element.)
200
What is the difference between Iron (II) oxide and Iron (III) oxide?
Iron (II) oxide is made using the Fe 2+ ion, and Iron (III) oxide is made using the Fe3+ ion.
200

What is a pure substance?

An element or compound. Contains one substance throughout. 

ex: helium or water

200
How many atoms are in the molecule: C6H12O6
6 C + 12 H + 6 O = 24 atoms
300
Explain the difference between the physical properties of malleability and ductility.
A substance is malleable if it can be pounded into sheets. A substance is ductile if it can be stretched into a long wire.
300
What group is the most non-reactive and where are they found on the periodic table?
Noble gases, Group 18
300

Name this compound (you can use the periodic table) and tell if it is covalent or ionic: CO2

carbon dioxide, covalent

300
What does the Law of Conservation of Mass tell us?
Mass of the reactants is equal to the mass of the products in a closed system.
300
What are the three types of subatomic particles within any atom?
Protons Neutrons Electrons
400
Name 3 chemical properties of any substance.
Reaction with acids Reaction to water Reaction to heat Behaviour in air Ability to burn
400
What is the name given to the most reactive group of non-metals and where is the group found in the periodic table?
The Halogens - group 17
400

Tell the name of this compound: Ca3P2

Calcium Phosphide 

400

What is a mixture?

Contains more than one type of particle. Contains two or more substances mixed together. Ex coffee grounds and water

400
If the atomic number of Lithium is 3, and the atomic mass of Lithium is 7, how many protons, neutrons and electrons does Lithium have?
Protons = 3 Electrons = 3 Neutrons = 4
500
What are 4 indicators that a chemical change has taken place?
Change in colour Change in smell Formation of a gas or solid (precipitate) Change in temperature
500

Name 4 physical properties of all metals, and identify where they are on the periodic table.

Metals are shiny, malleable, ductile, and conductors of electricity.

500

Describe a test that could be conducted to tell which metal is in a compound

Flame test. Based on the colour is burns, you can identify the metal

500

What is a heterogeneous mixture, and provide an example

A mixture where the composition is not uniform

ex; chocolate chip cookie
