Sodium and Chlorine = Sodium Chloride Potassium and Iodine = Potassium Iodide
group 1A
Sometimes these are called the "representative" elements.
Potassium and Hydrogen
The alkali metals. Group 1A.

because it has s1 configuration.
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 group 1a to 8a called representative elements. This is due to the fact that they portray as wide array of chemical and physical properties.
Alkali is a group of elements, not just one specific elements. Alkali metals are Group 1A elements starting with Hydrogen then lithium and so on.
valence electrons and electronic configuration.
Alkalene metals like hydrogen are present
