Question

Quizplus · Accepted Answer

Hydrogen is considered a unique element because it does not fit into any specific family due to its characteristics. While it is placed in the alkali metals group on the periodic table, it has many properties that differentiate it from this family. For example, it has only one electron in its outer shell, while other alkali metals have one valence electron. Therefore, hydrogen is often considered an outlier in terms of its properties and does not strictly belong to any one family.
