Introduction

Introduction Chemistry is the scientific study of the composition, structure, properties and reactions of matter that is constituted of atoms or subatomic particle and molecules.   Read more →...

Units

Units What is a unit? A unit is any standard used for comparison in measurements. Unit conversions allow for measurements of a property that have been recorded using different units (e.g., centimeters to inches). Why units are important? When describing a chemical reaction, units provide a standard measure to which we can refer. In other…...

The Metric System

The Metric System Metric System The Metric System is based on the fundamental units of measure for Length, Volume, Mass, Time, Electric Current, Temperature and Amount of a Substance. Quantity Units Unit Symbol Mass kilograms Kg Length Meters M Volume Liters L Time Seconds S Electric Current Ampere A Temperature Kelvin, Celsius K, C Intensity…...

Prefixes

Prefixes Base units in the Metric System can be converted into units that are more appropriate for the quantity being measured by adding a prefix to the name of the base unit. The common metric prefixes are given below. Prefixes are used to help in the description of a quantity of substance along with its…...

Atomic Structure

Atomic Structure Atoms are the building blocks of all matter. Every solid, liquid and gas is composed of these tiny particles. These atoms are said to be composed of tiny sub-atomic particles called protons, neutrons and electrons. The protons and neutrons are found in the nucleus surrounded by shells of moving electrons.  Protons have a…...

The Periodic Table

The Periodic Table It is important to note at this time that the table below lists all the elements of the periodic table and is a bit advanced. We will not be focusing on the transition metals series or any of the complexities of this table. Instead, we will be focusing on the first 20…...

Terms of the periodic table

Terms of the periodic table Element Name The purpose of the element name is obvious. The Periodic Table above and many others do not include element names. For those situations you must memorize the symbols that are related to each element name. Element Symbol Every element in the periodic table has a specific symbol that…...

First 20 elements

First 20 elements Now that we understand what symbols, atomic numbers and atomic masses are, we are ready to focus on the first 20 elements of the periodic table. A list of the first 20 elements is shown below: Element Symbol Atomic Number Atomic Mass Number of Protons Number of Neutrons Hydrogen H 1 1…...

Changes in the States of Matter

The states of matter, depending on the situation, can stay in one form or change to another. The change comes with extremes in temperature. These changes include: freezing, melting, boiling, evaporation, sublimation and condensation. Adding energy to matter causes a physical change. Energy is the capacity to cause change. Energy cannot be created or destroyed,…...
