Question

in its pure form, what state of matter is hydrogen? solid liquid gas

Explanation:

Hydrogen is a non - metallic element. Under standard conditions (temperature of \(25^{\circ}C\) and pressure of \(1\) atm), pure hydrogen exists as a diatomic molecule (\(H_2\)). Gases are substances with high molecular kinetic energy, where molecules are far apart and move freely. Hydrogen molecules have enough energy at standard conditions to overcome intermolecular forces and exist in a gaseous state. Solids have closely packed molecules with low kinetic energy, and liquids have molecules closer than in gases but with more freedom than in solids. Hydrogen does not fit the molecular arrangement and energy characteristics of solids or liquids under standard conditions.

Answer:

Gas
