Question

What is the difference between regular helium and helium 3?

Answer 1

Explanation:

Because of its low atomic mass of 3.02 atomic mass units, helium-3 has some physical properties different from those of helium-4, with a mass of 4.00 atomic mass units. ... Helium-3 boils at 3.19 K compared with helium-4 at 4.23 K, and its critical point is also lower at 3.35 K, compared with helium-4 at 5.2 K.

Answer 2

Both hydrogen-3 and helium-3 have \ the same nucleon number. The difference is that hydrogen-3 has two neutrons and one proton, while helium-3 has one neutron and two protons. ... A helium-3 atom has two protons and one neutron, while a helium-4 atom has two protons and two neutrons
