Reactions
The type of reaction where two or more substances combine to form a new compound.
A+B --> AB
What is an addition reaction?
An attempt to explain an observed phenomenon
What is construct a hypothesis?
The number that tells you how many electrons an atom of an element has.
What is the atomic number?
A combination of two or more chemically-bonded elements.
What is a Compound?
Formed when an electron transfers from one atom to another.
What are Ionic Bonds?
The type of reaction where a compound breaks down into two or more compounds
AB --> A+B
What is a decomposition deaction?
The step in the scientific method where you find out what other people have observed about the phenomenon.
What is do background research?
The oxidation rate for Halogens.
What is +1?
A combination of two or more atoms.
What is a Molecule?
Formed when an electron is shared from one atom to another.
What is a covalent bond?
A chemical reaction where a substance combines with oxygen to release energy, Carbon dioxide and water.
What is a combustion reaction?
The part of the scientific method where you test your hypothesis.
What is design and conduct an experiment?
The sum of the number of Protons plus Neutrons in the Nucleus.
What is The Atomic Mass?
The law that requires us to balance chemical equations. It states:
The total mass of the products of a reaction is equal to the total mass of the reactants.
The trend on the periodic table that indicates how much distance is between the nucleus and the outermost shell of an atom.
What is atomic Radii?
A chemical reaction where less energy is required to break the bonds in the reactants than is released when bonds are formed to make new products
What is an exothermic reaction?
This is what you do if your experiment supports your hypothesis.
What is Retest?
Columns or multiple columns in the periodic table.
What is a Group?
The rows on a periodic table are indicative this.
What is the capacity of the valence shell?
The type of bond that water has.
What is covalent?
A chemical reactions where ions from two compounds in solution exchange places to produce two new compounds.
What is a double displacement reaction?
This is what you do when your experiment does not support your hypothesis.
What is retest?
Beryllium, Magnesium, Calcium, Strontium, Barium, Radium.
What are Alkaline Earth Metals?
The pattern of valence electrons. (i.e. How many in the 1st, 2nd....)
The amount of energy required for reactants to form products.
What is Activation Energy ?
