Hel (He, łac. helium) – pierwiastek chemiczny o liczbie atomowej 2, z grupy helowców (gazów szlachetnych) w układzie okresowym [4]. Jest po wodorze drugim najbardziej rozpowszechnionym pierwiastkiem we wszechświecie, jednak na Ziemi występuje wyłącznie w śladowych ilościach.
19 gru 2023 · According to the Molecular Orbital Theory, the Helium Formula is not written as He2. However, the Helium gas formula He2 is sometimes correct because, in the liquid phase, the Van Der-Waal force between them becomes dominant. At normal pressure, liquid helium does not solidify irrespective of the temperature. Isotopes of Helium.
