What are the elements in groups 1A to 8A called?

Some of these groups have special names. The elements in group IA are called the alkali metals. The elements in group IIA are called the alkaline earth metals. The elements in group VIIA are called the halogens and the elements in group VIIIA are called the noble gases or the inert gases.

What does 1A 8A mean on the periodic table?

Families: 1A – alkali metals. 2A – alkaline earth metals. 7A – halogens. 8A – noble gases.

What are elements 1B 8B called?

the transition metals
The elements in groups 1B through 8B (also known as 3 through 12) are called the transition metals. Sometimes this block of elements are referred to as the d block. They are called d block elements because the electrons being added in this block of elements are being added to the d orbitals.

What are the groups for 1A/2A 7A and 8A?

Some groups have special names:

  • Group 1A: Alkali metals.
  • Group 2A: Alkali earth metals.
  • Groups 3B-2B: Transition metals.
  • Group 7A: Halogens.
  • Group 8A: Noble gases.

What is the name for the 1A group?

The Alkali Metals
Group 1A (or IA) of the periodic table are the alkali metals: hydrogen (H), lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). These are (except for hydrogen) soft, shiny, low-melting, highly reactive metals, which tarnish when exposed to air.

What are the common names of groups 1A/2A 7A and 8A?

What is group 1A on the periodic table?

Group 1A (or IA) of the periodic table are the alkali metals: hydrogen (H), lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). These are (except for hydrogen) soft, shiny, low-melting, highly reactive metals, which tarnish when exposed to air.

What are groups 1A through 7A referred to and why?

Elements in groups 1A through 7A are often referred to as representative elements because they display a wide range of physical and chemical properties. The s and p sublevels of the highest occupied energy level are not filled. The group number equals the number of electrons in the highest occupied energy level.

What are 1A 3B and 7A?

The periodic table have the groups and periods. In the periodic table, there are 7 horizontal rows of elements are known as period and 18 vertical columns of elements are known as group. Hence, 1A, 3B, and 7A are examples of group number on the periodic table.
