The Periodic Law
The vertical columns of the periodic table are called these.
What are groups?
These are the electrons that are the furthest from the nucleus.
What are valence electrons?
This number hangs next to the element symbol, indicating how many atoms are in the molecule.
What is the subscript?
The name for the substances at the start of a chemical reaction.
What are reactants?
The answer to this song sung by the teacher is "The Molar Mass!!!". And you find it on the periodic table.
What do you use if you want to go from grams to moles or moles to grams?
These types of elements are above the stairs on the right side of the periodic table.
What are non-metals?
These are the three types of bonds.
What are ionic, covalent, and metallic?
This is the name for the following chemical formula: BaO
What is barium oxide?
The number in the chemical equation that is added or changed to balance the equation.
What is a coefficient?
This is the name of the reactant that runs our first.
What is the limiting reactant?
These are the horizontal rows of the periodic table.
What are periods?
These atoms have gained or lost an electron.
What are ions?
This is what to do after you write the formula and the charge; check to see if the charges are balanced and the charges are NOT balanced.
What is criss-cross the charges?
What are catalysts?
This type of yield can only be determined by experiments.
What is actual yield?
This is the name of the group 18 elements that are not reactive.
What are noble gases?
This type of covalent bond is where there is unequal sharing of electrons.
What are polar bonds?
These are two or more atoms bonded together that also have a charge. They can be found on the back of the periodic table.
What are polyatomic ions?
This type of reaction is where one reactant breaks apart into two or more products.
What is a decomposition reaction?
The actual yield divided by the theoretical yield multiplied by 100.
What is the percentage yield?
These types of metals include groups 3-12 on the periodic table.
What are transition metals?
This is the strongest intermolecular force between polar molecules. It also is F O N!!
What is Hydrogen Bonding?
This is the formula of the diarsenic pentoxide.
What is As2O5?
These are the two products of every complete combustion reaction.
What are carbon dioxide and water?
The number of mole ratios that can be correctly obtained from the following chemical equation: 2Al2O3(l) → 4Al(s) + 3O2(g).
What is 6?
