Sorted by:  

Common Functional Groups in Organic Chemistry

In organic chemistry, functional groups (or reactive centers) are small structural units within molecules that dictate how most of the compound's chemical reactions occur. Know these common functional [more…]

Periodic Table of Elements

If you’re studying organic chemistry, the periodic table is an important tool. The elements and their atomic numbers are listed and grouped together by their properties — making it easier to remember without [more…]

Chemistry Concepts: Energy Levels and Orbitals

A lot of chemistry is explained by the sharing and trading of electrons between atoms. Understanding how electrons are arranged in an atom is a building block of Chem I. [more…]

Digging the Mole Concept in Chemistry

The mole (abbreviate mol and sometimes called Avogadro's number) is a conversion number that allows a chemist or chemistry student to move from the microscopic world of atoms, ions, and molecules to the [more…]

Identifying Isotopes through Representations

In Chem I, you may have to identify isotopes, which are atoms of the same element that have different numbers of neutrons. The following representation allows you to identify a specific isotope of an element [more…]

Common Measurement Conversions for Chemistry

In order to succeed in your Chem I class, you need to have a firm understanding of basic chemistry measurements and how to convert them from one measurement to another. Following are some important conversions [more…]

The Basic Chemistry of Acids and Bases

A lot of chemistry requires you to understand the difference between acids and bases. An acid is a substance that donates an H+ ion to another chemical species called a base. A [more…]

The Combined Gas Law and Ideal Gas Law

When studying the properties of gases, you need to know the relationships between the variables of volume (V), pressure (P), Kelvin temperature (T), and the amount in moles [more…]
