Any given element will exhibit analogous behavior to the eighth element following in the table.
What is The law of octaves?
100
A regular variation in the properties of an element with increasing atomic numbers. It is attributed to regular variations in the atomic structure of each element.
What is Periodic Trend?
100
Mass is neither created nor destroyed in any ordinary chemical reaction.
What is Law of Conservation of Matter?
100
Maximum amount of product that can be produced from a given amount of reactant.
What is Theoretical Yield?
100
When one or more substances have undergone a change in identity.
What is Chemical Reaction?
200
Discovered the Halogen triad (Cl, Br, I) and Alkali triad (Li, Na, K). Proposed the law of triads.
Who is Johann Dobereiner?
200
Energy change that occurs when an electron is added to a gaseous atom. Atoms with stronger effective nuclear charge, have greater this.
What is Electro Affinity?
200
AB --> A + B. A single compound undergoes a reaction that produces two or more simpler substances.
What is decomposition?
200
(actual yield / theoretical yield) * 100
What is Formula for Percentage Yield?
200
CaCO3 --> CaO + CO2. Balanced equation?
What is CaCO3 --> CaO + CO2?
300
States that there is a periodic recurrence of chemical and physical properties of the elements when the elements are arranged in order of increasing atomic weight.
What is Periodic Law?
300
Distance from nucleus to outer most shell. Its pattern down a group increases and across the period decreases.
What is Ionic Size?
300
A substance combines with oxygen releasing a large amount of energy i the form of light and heat.
What is Combustion?
300
mass given * molar mass of given/1 mol * moles of unknown/moles of given * molar mass of unknown/1 mol =
What is Mass - Mass Calculation?
300
Conversion factor that relates the amounts in moles of any two substances involved in a chemical reaction.
What is Molar Ratio?
400
Elements in column 1A in the periodic table.

400
Ways to balance equations.
What is Induction and Algebraic Method?
400
The substance that is not used up completely in a reaction.
What is Excess reactant?
400
A branch of chemistry that deals with the relative quantities of reactants and products in chemical reactions.
What is Stoichiometry?
500
Third block in the periodic table. From left to right.
What is P block?
500
These decrease by moving top to botton on the Periodic table.
