helium

Today, balloons in Japan are lifted by hot air rather than the more expensive helium or hydrogen.

Because it is chemically inert, helium was not identified on Earth until some time later, in 1895.

There he worked with Born on atomic theory, writing a joint paper with him on helium .

The atomic elements heavier than hydrogen and helium could not have been produced during the inferno of the Big Bang.

Even though helium is twice as dense as hydrogen, this is less than one metric ton of gas.
