Question

In the core of the sun, nuclear fusion combines hydrogen atoms to make helium atoms. What can you infer about helium from this?

A-Helium is lighter than hydrogen.

B-Helium is heavier than hydrogen.

C-Helium is heavier than oxygen.

D-Helium is heavier than carbon.

Answer 1

It is lighter.

Answer 2

My answer would be

B.

Step-by-step explanation:

Although helium is twice as heavy as (diatomic) hydrogen, they are both significantly lighter than air, making this difference negligible. The lifting power in air of hydrogen and helium can be calculated using the theory of buoyancy as follows: Thus helium is almost twice as dense as hydrogen.
