A metal with a water-soluble base is known as an alkali metal. The oxide mineral of an element is referred to as “earth”. An alkali earth metals means a metal that has the same oxide content as an alkali. The hydroxide of the metal should be behaving like an alkali if it has alkali properties.
Normal oxides can be formed when oxygen in the atmosphere interacts with alkali metals. Hydrogen is a block element from the first group and the first-period element. If you have the same valence electron as alkali metals, you don’t have any other properties that are similar to alkali metals.
The position of hydrogen is controversial because it is the only element with no neutrons. It is placed above the group in the periodic table because it has similar electronic configuration to the alkali metals. It forms cations more reluctantly than the other alkali metals
The current position of hydrogen with alkali metals isn’t justified since it shows some of the properties of the metals. Not all of the properties of hydrogen are the same as those of alkali metals. It’s similar to halogens in that it makes diatomic and covalent compounds.
