Chemistry Digital Concept Map
Periodic Table
A structured arrangement of elements containing information about every element like atomic mass and number. The periodic table was first introduced in 1869.

Group
A group is a column on the periodic table in which all of elements have similar properties. Ex. Noble Gasses, Halogens, Alkaline Earth Metals.
A group is a column on the periodic table in which all of elements have similar properties. Ex. Noble Gasses, Halogens, Alkaline Earth Metals.
Period
A metal is an element found on the left side of the periodic table. Metals lose electrons to non-metals when they form ionic bonds. Alkali Metals and Alkali Earth metal are two groups of metals.
Metal
Non-Metal
A non metal is an element found on the right side of the periodic table. They gain electrons from metals when forming ionic bonds and also share electron with other non-metals to form covalent bonds.
Metalloids
Metalloids are the group of metals that are found between metals and non-metals. They have properties of both metals and non-metals.
Ion
An ion is an atom that has either more or less electrons than protons. If an ion has more protons, it is positive. If an ion has more electrons, it has a negative charge.
Electron
A negatively charged particle that moves around the nucleus of an atom at different energy levels, or orbits. Electrons were first discovered by Ernest Rutherford in 1897.
Element
A pure substance that cannot be broken down into a simpler substance. Elements can all be found on the periodic table.
Proton
A proton is a positively charged particle that can be found in an elements nucleus. Protons were
discovered by J.J. Thomson

Neutron
A neutron is a neutral particle that is found in an elements nucleus. It was discovered by James Chadwick, the man Jimmy Neutron got his name from.

Halogen
Halogens are a group of non-metals that are missing only one electron from there valence shell. As a result of this, they are very reactive. They often form covalent bonds with other halogens are take one electron away from metals when forming ionic bonds.

Noble Gas
Noble Gases are a group of non-metals that are found on the far right side of the periodic table. They have full valence shells which cause them to be very nonreactive.

Alkali Metal
Alkali Metals is a group of metals found in the furthest left group of the periodic tables. Alkali metals only have one electron in their valence shell which they lose when forming ionic bonds. Lithium is an alkali metal.

Ionic Compound
An ionic compound is a compound formed when a non-metal takes an electron from a metal in order to fill it's valence shell.

Molecular Compound
A molecular compound is a compound formed by two non-metals with a covalent bond.

Alkaline Earth Metal

Alkaline Earth Metals are found in the second group on the left side of the periodic table, beside Alkali Metals. Alkaline Earth Metals have two electrons in their valence shells which they lose when forming ionic bonds. Beryllium is an Alkaline Earth Metal.
Law of Conservation of Mass

A scientific law that states that the total mass of the reactants in a chemical reaction is always equal to the total mass of the products.
Reactant

The starting material in a chemical reaction. For example, oxygen and a hydrocarbon in a combustion reaction.
Product

The substance produced in a chemical reaction. Water and carbon dioxide in a chemical reaction.
Acids

A substance that tastes sour, turns blue litmus paper red, reacts with some metals to produce hydrogen gas, is a good conductor of electricity in solution and reacts with a base to produce a salt and water. Acids have a pH number that is less than 7.
Bases

A substance that tastes bitter, feels slippery, turns red litmus paper blue, is a good conductor of electricity in solution and reacts with an acid to produce a salt and water. Bases have a pH number greater than 7.
pH

A number that can be used with the pH scale to determine if the substance is an acid or a base. 0 is the most acid and 14 is the most basic. 7 is neutral.
Combustion

The chemical reaction that occurs when a substance reacts very quickly with oxygen to release energy. The formula for a hydrocarbon experiencing combustion is fuel + oxygen -> oxides + energy
Synthesis

A chemical reaction in which two or more elements or compounds combine to form a single compound; also called a combination reaction
Decomposition

A chemical reaction in which two or more elements or compounds combine to form a single compound; also called a combination reaction
Single Displacement

A chemical reaction in which one element displaces, or replaces, another element in a compound.
Double Displacement

A chemical reaction that occurs when elements in different compounds displace each other or exchange places to form two new compounds.
Neutralization
A chemical reaction in which the reactants are an acid and a base and the products are water and a salt. Neutralization reactions remove acidic and basic properties from compounds.
