Helium is a noble gas in row 1 that has 2 valence electrons, glows red-orange in an electric field, and is found in the sun.
The gas you are describing is helium.
Helium belongs to the noble gas family and is in row 1 of the periodic table.
It has only 2 valence electrons, which explains its low reactivity.
When placed in an electric field, helium atoms can absorb energy and emit light.
This light appears as a red-orange glow.
Helium is also found in the sun and is the second-most abundant element in the universe.
It was first discovered in 1868 and is commonly used to inflate balloons.
