Halogens are found in this group of the periodic table.
What is group VII? (7 or 17 also accepted).
100
This type of change does not result in a change at the subatomic level. It is only a rearrangement of the particles.
What is a physical change?
100
glucose + oxygen ---> carbon dioxide + water
What is a decomposition reaction?
100
This is the formula for potassium phosphate.
What is K3(PO4)?
100
This is the name given to a shared group of electrons.
What is a covalent bond?
200
These are very stable elements (with a full outer orbital) that do not react with other substances.
What are noble gases?
200
A gas produced, precipitate forming, a new odour, energy released, or a change of colour could each be evidence of this.
What is an indication of a chemical change?
200
hydrogen + oxygen -> water is an example of this type of reaction.
What is synthesis?
200
This is the name for Mg3(PO4)2
What is magnesium phosphate?
200
This is a very common molecular compound made from the synthesis of hydrogen gas with oxygen.
What is water?
300
These kinds of elements do NOT give electrons up easily making them negatively charged as ions. They are given the ending "-ide" in ionic compounds.
What are non-metals?
300
Colour, transparency, and lustre are examples of this kind of property.
What is physical?
300
sulphuric acid + potassium hydroxide ---> water + potassium sulphate. This is an example of this type of reaction.
What is neutralization?
300
This is the formula for manganese (IV) sulphide.
What is MnS2?
300
This is the prefix used for "4".
What is tetra?
400
These elements are found along the diagonal between metals and non-metals on the periodic table (and show certain properties of both).
What are metalloids?
400
This is the name given to a solid formed out of two solutions.
What is a precipitate?
400
lead (II) nitrate reacts with potassium iodide to form a precipitate of lead (II) iodide and a solution of potassium nitrate. This is an example of this kind of reaction.
What is a double displacement reaction?
400
This is the name of CrN
What is Chromium (III) nitride?
400
This is the name of PF5
What is phosphorus pentafluoride?
500
This is the name for electrons found in the outermost orbital.
What is "valence"?
500
A change of state is an example of this.
What is a physical change?
500
zinc + copper sulphate --> zinc sulphate + copper. This is an example of this kind of reaction.
What is single displacement?
500
This is the name of Ni(SO4)?
What is nickle (II) sulphate?
500
This is the name given to very common molecular compounds made from chains of hydrogen and carbon.
