you can do the Chewing Gum experiment.
Helium has one kind of atom: helium.
None, theoretically
Helium-3 is used in experiments for nuclear fusion, neutron detection, cryogeny installations and RMN for medical use.
nuclear fusion of hydrogen to form helium
Helium is no metal, but a gas (at room temperature at least).
nonmetal
Uses of helium: balloons, lasers, protective atmosphere, welding, leak detection, MRI, filling gas in nuclear fuels, physics experiments, etc.
Heike Kamerlingh Onnes, who discovered and named the phenomenon during his experiments with liquid helium
Helium is a noble gas and does not typically form charged ions in its natural state. However, helium can be ionized under high-energy conditions, such as in a plasma state or in certain scientific experiments.
helium and uranium.
Most experiments conducted are medical experiments, but fluid mechanics experiments, various experiments involving weightlessness, and testing of new technologies are also conducted.
Why helium, of course!
