What are the three general groups on the periodic table?

Periodic Table Groups. Group 1: Alkali Metals. Alkali metals are soft, ductile, and good conductors of electricity and heat. This group includes the elements Lithium, Sodium, Potassium, Rubidium, Cesium, and Francium. Alkali metals are very reactive. Compared to other elements they have a low melting and boiling point. Group 2: Alkaline Earth ...

What does the group number represent in the periodic table?

The group number in the periodic table represents number of valence electrons of the elements in a certain group. For example, all the elements in Group−1 have 1 electron in their outer most shell.

What are the groups and families on the periodic table?

The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties. The horizontal rows on the periodic table are called periods. Group (family): A vertical column in the periodic table.

How are groups on a periodic table numbered?

the main groups are numbered from 1 to 7 going from left to right, and the last group on the right is Group 0; ... Only elements are found in the periodic table, never compounds. For example ...

Back to Elements List. Group. See About the Periodic Table for information on how Group can be used to characterize an element.. Group 1: alkali metals, or lithium family; Group 2: alkaline earth metals, or beryllium family; Group 3: the scandium family

How many groups are there in the periodic table?

Groups are the vertical columns on the periodic table. There are total 18 vertical columns on periodic table. Hence there are 18 groups. The elements lying in the same groups show similar chemical properties and they also have same number of valence electrons.

What is the first group of elements in the periodic table?

Group 1: Alkali metals group. Alkali metals group is the very first group (group 1) on the periodic table. The elements included in the Alkali metals group are; Lithium (Li)

Why are the elements in the bottom two rows of the periodic table included in group 3?

The elements in the two bottom rows of the periodic table are also included in these groups. They are placed in the two separate rows at the bottom because they show few different properties. Actually, the elements in the bottom rows are the extension of group 3 only. So they are included in group 3. But as these elements have few different ...

What is the oxygen group on the periodic table?

Oxygen group is the group 16 on the periodic table.

What is an example of group 18?

Example of group 18. All the elements of group 18 are chemically inert (that means they do not easily react with other elements). And all the elements of group 18 have a complete octet (that means they have 8 electrons in their outer shell).

Which group is alkaline earth metals?

Alkaline earth metals are the group 2 elements on the periodic table.

Can you find every detail of an interactive periodic table?

You can effortlessly find every single detail about the elements from this single Interactive Periodic table.

Why is the 13th group also called a boron group?

The 13th group is also called a boron group because it is only metalloid present in the group.

What decreases from left to right within a period and increases from top to bottom within a group?

Atomic radius decreases from left to right within a period and increases from top to bottom within a group.

Answer

A group is a vertical column of the periodic table based on the organization of the outer shell electrons. There are a total of 18 groups. From left to right in the periodic table, there are two groups (1 and 2) of elements in the hydrogen block, ten groups (3 through 12) in the transition block, and six groups (13 through 18) in the main block.

What is the periodic table?

A periodic table is an arrangement of elements based on their atomic numbers and chemical properties.

How are the elements in the periodic table arranged?

The elements in the periodic table are arranged horizontally in ascending order of their atomic numbers.

How many groups are there in the periodic table?

Groups are the vertical columns on the periodic table. There are total 18 vertical columns on periodic table. Hence there are 18 groups. The elements lying in the same groups show similar chemical properties and they also have same number of valence electrons.

What is the first group of elements in the periodic table?

Group 1: Alkali metals group. Alkali metals group is the very first group (group 1) on the periodic table. The elements included in the Alkali metals group are; Lithium (Li)

Why are the elements in the bottom two rows of the periodic table included in group 3?

The elements in the two bottom rows of the periodic table are also included in these groups. They are placed in the two separate rows at the bottom because they show few different properties. Actually, the elements in the bottom rows are the extension of group 3 only. So they are included in group 3. But as these elements have few different ...

What is the oxygen group on the periodic table?

Oxygen group is the group 16 on the periodic table.

What is an example of group 18?

Example of group 18. All the elements of group 18 are chemically inert (that means they do not easily react with other elements). And all the elements of group 18 have a complete octet (that means they have 8 electrons in their outer shell).

Which group is alkaline earth metals?

Alkaline earth metals are the group 2 elements on the periodic table.
