What is groups 1 and 2 in the periodic table called?
Group 1 in the periodic table is called the alkali metals, and Group 2 is called the alkaline earth metals. These groups of elements share similar chemical properties due to the number of electrons in their outermost energy level.
What column number on the periodic table are elements called alkali metals?
This is the group 1.
What is the number of valence electrons for Alkali Earth Metals?
Alkali Earth metals have a single valence electron, and are found in the first group.
What happens to the chemical reactivity of alkali metals as you increase atomic numbers?
The chemical reactivity of alkali metals increase when the atomic number increase.
What is the group number of alkali earth metals?
