Helium
Helium does not burn. It is an extremely stable noble gas. Only in a nuclear reactor can it be made to react.
Helium is a gas which is very light. It is the second lightest element in the universe. Helium was discovered in 1986. William Ramsay confirmed it was helium. Helium remains as gas up to 25c (77f). Helium has no taste or no color. Helium doesn't combine with other elements. It is a by product of the reaction of hydrogen in the sun.
The real colour of sun would be yellow because the Helium spectrum lies in the yellow region and sun consists of a lot of Helium.
