  Elemental gases

  Posted by Encyclios on April 24, 2023 at 7:59 AM

  The only chemical elements that are stable diatomic homonuclear molecules at standard conditions for temperature and pressure are hydrogen (H₂), nitrogen (N₂), oxygen (O₂), and two halogens: fluorine (F₂) and chlorine (Cl₂). When the pressure is changed and is higher or lower, or when the temperature is changed and is higher or lower, then the element may exist in a different form such as in liquid form or solid form. When grouped together with the monatomic noble gases – helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn) – these gases are called “elemental gases”.
