to prevent the table from getting too wide for a reasonable sized sheet of paper
The square for hydrogen is separated because it is both a nonmetal and a member of the alkali metals group, and therefore exhibits unique properties that differentiate it from the other elements. Its placement acknowledges its distinct characteristics and helps to highlight its anomalous behavior compared to the rest of the alkali metals.
No, hydrogen is not the only non-metal in its family. In the periodic table, hydrogen is placed in group 1 along with the alkali metals, but it behaves differently from the rest of the group due to its unique properties.
As I understand it scientists took an educated guess at the Hydrogen Atom and all the rest were extrapolated from there.
It doesn't entirlely stand alone. there is no gap from hydrogen and the rest of the table. Hydrogen is just simply singular. It only has one proton. No neutron. One of a kind. even though I believe deutrium to be number 2 on the table rather than helium. And neutronium should be classified as element 0. Should be categorized in the periodic tables at all time.

A value separated from the rest of the data is called an outlier
No, hydrogen is not the only non-metal in its family. In the periodic table, hydrogen is placed in group 1 along with the alkali metals, but it behaves differently from the rest of the group due to its unique properties.
Italy is separated from the rest of Europe by the Alps.
The Alps separate Russia from the rest of Europe.
Even though hydrogen has a vacant electron in its outer shell, like many of the elements in group 1 of the periodic table, it has unusual properties, e.g. it is a gas at room temperature, whereas the other elements are all solid. As a result, some forms of the periodic table show hydrogen above the rest in the table, in its own special place. However, it is still in group 1

outlier
The two rows at the bottom of the periodic table, known as the f-block, are separated to conserve space. They contain the lanthanides and actinides series of elements and would make the rest of the periodic table too wide if included. These rows are still part of the periodic table, but they are usually shown below as a separate section for convenience.
