Periodic Table Groups and Periods Archives - Dynamic Periodic Table of Elements and Chemistry

As you know, a periodic table is a tabular arrangement of elements into groups and periods. There are different Periodic Table Group Names given to each group or family of elements.

Groups are the horizontal columns which are 18 in number. They are arranged in a manner in which all the elements in a group are said to belong to the same group or family. Also as we go from top to bottom in a periodic table, the valency of the elements increases.

Since each group has similar properties, all the group can be categorized into families. For example, the first group is said to belong to the lithium family

Periodic Table Groups and Periods

A group in a periodic table is the horizontal column from top to bottom across a periodic table. There are 7 groups across a periodic table. Each group has elements which have similar chemical properties and thus belong to the same family of elements. For example, the first group is of the lithium family, and the second group is of Berillium group.

The rule followed by the elements across a group is that the valency of the elements increase as one goes from top to bottom across a periodic table.

A period is a vertical row across a periodic table. All the elements across a period have the same number of electron orbitals. A rule followed by the elements of a group is that the metallic property of an element decreases as one goes from left to right across a period. And like a group, the valency of element increases as one goes from left to right across a period.

Here is a table depicting period across a periodic table

What Is A Group On The Periodic Table

Here we are going to share with you a table depicting the group in a periodic table.

What Is A Group On The Periodic Table

Hello friends! As you know, the periodic table is an important concept in chemistry and science. So Today we shall talk about How Many Periods Are In The Periodic Table. A period in a periodic table is the horizontal row depicting elements with similar chemical properties.

There are 7 periods in a periodic table. As we go across each period from left to right, the elements show similar chemical and physical properties and the atomic number of the elements increases.

Periodic Table Groups and Periods

In chemistry, periods and groups are two ways to categorize the elements. Groups are the vertical columns in the periodic table, while periods are horizontal rows across the periodic table. The groups and periods follow certain rules with regard to the properties of elements. As you move down in a group, the atomic number increases. When you move from left to right across a group, the atomic number increases then too.

What Do Group And Period Mean in the Periodic Table

Groups are the vertical columns in the periodic table, while periods are the horizontal rows across the periodic table. The rule followed by the group is that all the elements belonging to the same group have the same valency. And all the elements across a period have the same number of atomic orbitals.

Difference Between a Group And a Period on the Periodic Table

Both in groups and periods, the atomic number increases as one moves downwards or towards the right. There are 18 groups in a periodic table, while the number of periods is 8.

In a period, as one goes from left to right, the element loses its metallic properties and becomes less metallic than its predecessor. While groups are used by chemists to determine a family of elements since they have similar chemical properties and the same number of electrons in their outer shell. For example, the first group (Group 1 ) belongs to alkali metals.
