They're called the alkali metals, and are comprised of lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and Francium (Fr). Group 1A also includes hydrogen (H), though that isn't an alkali metal.
Sodium and Chlorine = Sodium Chloride Potassium and Iodine = Potassium Iodide
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.
There are 7 elements in group 1: hydrogen, lithium, sodium, potassium, rubidium, cesium, and francium. All of these (except hydrogen) are considered alkali metals. They react very easily with other elements.
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.

This is the alkali metals family.
Potassium and Hydrogen
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.
This is not a reliable source.. Go get an encyclopedia.
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.
The most reactive metals are the alkali metals in group 1a.
