Hihi i need to know if helium mixes with Sodium.
Helium has a valence of zero and is chemically unreactive under all normal
conditions.It is an electrical insulator unless ionized.So it can not reack with
sodium. But when temperature will be higher
than 1156 K(, 883 °C, 1621 °F boiling point of Sodium),Sodium and Helium will
formed mixture of gases.
