Hello! My name is Dmitri Mendeleev! I created the first version of the periodic table of

elements.

Today I am going to explain how the periodic table is organized. Also, I

will describe how you can determine the properties of

individual elements and how they react with each other!

Let’s get started! Click below to learn more!

Organization

The table is divided into three different types of elements: metals, nonmetals, and metalloids.

Metals are solids that make up a majority of the elements. They are shiny, malleable (can be rolled), ductile(can be drawn into wires), and good conductors.

Nonmetals are not solid at room temperature. They are not shiny, malleable, ductile and they do not conduct electricity.

Metalloids are the elements located between the metals and nonmetals. Therefore, they have properties of both types of elements.

Oxidation State

The oxidation state, also known as the oxidation number, is the charge on an atom. It can be determined for elements based on their position in the periodic table.

Groups (columns) in the periodic table have similar properties and charges.

For example: Group 1 is 1+, Group 2 is 2+, etc. One exception is Group 4. These elements can be 4+ or 4-.

Ionic Bond

An ionic bond occurs when one element gives its electrons to another element. This type of bond usually occurs between a metal and nonmetal.
