Answer:
Alkali metals are: Lithium(Li), Sodium(Na), Potassium(K), Rubidium(Rb), Cesium(Cs) and Francium(Fr).
Explanation:
I cant understand your question mate, but these are all the alkali metals, because they are in the first group. Note that Hydrogen(H) is not an alkali metal. Hope that helps. God bless you.
The alkali metals are lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).
What is the periodic table?
The periodic table has been the arrangement of the elements based on the reactivity and the electrons in the valence shell.
The left side of the periodic table has been consisted of the metals, while moving from left to right the metallic character decreases and the nonmetallic character increase.
The group 1 of the periodic table has been consisted of the metals with 1 valence electrons. The group has been termed as alkali metals, as the reaction of the elements of this group with water forms alkali.
The elements belonging to group 1 of the periodic table are lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).
