My Description on how Hydrogen is used in the modern world. (5-8 sentences)

             Hydrogen is the lightest element in the periodic table. It has the chemical symbol of H and it has the atomic number 1. Even though the elements in Group 1 are alkaline metals, the list of alkaline metals start from Lithium down. So Hydrogen is not an alkaline metal, it’s a non-metal specifically a gas. Hydrogen as water is important for Human life. Hydrogen gas was used in lighter-than-air-balloons for transportation, but it was far too dangerous because of the fire risk.
