The group 1 of the Periodic Table of Mendeleev is called alkali metals and contain lithium, sodium, potassium, rubidium, caesium, francium.
Group 1A elements are alkali metals like sodium and potassium, which are highly reactive and metallic. Group 7A elements are halogens like chlorine and fluorine, which are highly reactive nonmetals.
Hydrogen is placed with the elements in group 1A (1) because it has one electron in its outermost shell, similar to other group 1A elements like lithium, sodium, and potassium. However, hydrogen is unique as it is not a metal like the other elements in this group, exhibiting properties of both metals and nonmetals.
The elements in group 1A of the periodic table are lithium, sodium, potassium, rubidium, cesium, and francium. These elements are known as the alkali metals and have similar chemical properties due to their tendency to form ions with a +1 charge.
The elements in groups 1A to 8A are called the representative elements or main group elements. Each group corresponds to a specific column on the periodic table and has similar chemical properties due to their electron configurations.
Hydrogen is separate from the rest of Group 1A elements because it displays unique properties that do not fit the typical characteristics of alkali metals (Group 1A elements). For example, hydrogen can form both positive and negative ions, while other Group 1A elements typically form only positive ions. Additionally, hydrogen can exhibit nonmetallic properties in addition to metal-like behavior, setting it apart from the rest of Group 1A.

group 1A on the periodic table? that should be the alkali metals. i just learned that in class. lol.

Potassium and Hydrogen
This is the alkali metals family.

Elements in the sodium family (Group 1A or Group 1) have 1 valence electron. This is because they have one electron in their outermost energy level.
This is not a reliable source.. Go get an encyclopedia.
The most reactive metals are the alkali metals in group 1a.
