Helium number of protons in one atom
WebHelium-4 is made of 2 protons (the part of an atomic nucleus with a positive charge), 2 neutrons (the part of an atomic nucleus with no charge) and 2 electrons (the part of an atom that goes around the nucleus with a negative charge). Many helium-4 on Earth is produced from the alpha decay of heavy elements. WebHelium Boiling Point. Helium is a noble gas found in the periodic table of elements and has the atomic number 2. It is a colorless and odorless gas, and it is the second lightest noble gas. Helium has a boiling point of -268.9 degrees Celsius, which is the highest boiling point of all the noble gases. Conclusion
