Chemistry Review Jeopardy
Chemical symbol for lead.
What is “Pb”.
mass Volume
What is the formula for calculating Density.
Other than “difficult to reverse”, these are four indicators of a chemical
change.
1. Colour change.2. Precipitate forms.3. Gas is formed (usually
indicated by bubbles/effervescence).
4. Energy (heat or light) is given off.
The period (row) number tells you this.
What is the number of orbits/shells.
In an atom, the number of protons = the number of
electrons, which is equal to…
The Atomic Number.
The ionic charge is determined by the
group/column number, which relates to this important
information.
What is the number of valence (last orbit) electrons.
Group 1 metals.
What is Alkali Metals.
Group seven nonmetals.
What are the Halogens.
A metal + a nonmetal forms this kind of compound.
What is an Ionic Compound.
Charge for Lithium.
What is 1+.
Charge for Sulfur.
What is 2-.
Show how aluminum and oxygen form a compound,
write the chemical formula.
Al3+ O2-
Al2O3
Name this compound: MgF2.
What is Magnesium fluoride.
These elements are most commonly found as diatomic compounds (two of the same
element).
What are: H, N, O, F, Cl, Br, I.
What’s the difference between an Ionic bond and a
Covalent bond?
Ionic bonds are between two ions, formed when electrons
are given/taken; Covalent bonds are stronger, between two nonmetals, and formed
by the sharing of two valence electrons.
These elements do not generally react.
What are the Noble Gases (group 8).
Draw a Bohr-Rutherford diagram for Phosphorus.
State, lustre, odour, texture, malleability, density, etc. are
examples of…
What are “physical properties”.
The information that a subscript tells you.
How many atoms of the element to the left.
A coefficient number is located here and tells you…
In front (to the left) of the chemical formula, and tells you how many molecules
there are.
How many atoms of hydrogen are in a molecule of glucose?
What is 12.
Ammonium sulfate, (NH4)2SO4 has this many atoms of each
element…
2 Nitrogen8 Hydrogen1 Sulfur4 Oxygen
A glowing splint that re-ignites indicates that this gas is
present.
What is Oxygen.
How do you test for Hydrogen gas?
Place a flaming splint to the mouth of the test tube and listen for a “popping” noise.
