Admin Which groups of elements are in the main group?
The main group elements are groups 1, 2, and 13-18 on the periodic table. The main group elements are the chemical elements belonging to the s-block and p-block on the periodic table. These are elements in group 1 and group 2 (s-block) and groups 13 through 18 (p-block).
What are main group elements examples?
Specific examples of main group elements include helium, lithium, boron, carbon, nitrogen, oxygen, fluorine, and neon.
Is aluminum a main group element?

What are the characteristics of Group 1 elements?
General physical properties of Group 1 elements: Alkali metals are grey solids with shiny silvery surfaces when freshly cut. Alkali metals are soft solids and can be easily cut. Alkali metals have low densities as compared to heavy metals such as iron and copper. Alkali metals are good conductors of heat and electricity.
What do all elements in Group 1 have in common?
Although many characteristics are common throughout the group, the heavier metals such as Ca, Sr, Ba, and Ra are almost as reactive as the Group 1 Alkali Metals . All the elements in Group 2 have two electrons in their valence shells, giving them an oxidation state of +2.
