It says: "electrons, protons, neutrons, helium nuclei..." (Helium, not hydrogen.)dotancohen said:I thought that the hydrogen nucleus is just a single proton. So why does this page mention "electorns, protons, hydrogen nuclii", etc?
A proton is a subatomic particle with a positive charge, found in the nucleus of an atom. A hydrogen nucleus, also known as a hydrogen ion, is a single proton that has lost its electron. Therefore, a hydrogen nucleus is essentially just a lone proton.
Protons and hydrogen nuclei are essentially the same thing. The only difference is that a hydrogen nucleus is a single, isolated proton, while a proton is found in the nucleus of an atom.
Yes, protons and hydrogen nuclei can be found in the nuclei of different elements. For example, hydrogen, the first element on the periodic table, has an atomic number of 1, meaning it has one proton in its nucleus. However, other elements, such as carbon, have multiple protons in their nuclei.
Protons and hydrogen nuclei behave similarly in different environments because they both have a positive charge and are affected by electromagnetic forces. However, a hydrogen nucleus, being a single proton, is more easily influenced by these forces compared to a proton that is bound in an atom's nucleus.
No, protons and hydrogen nuclei are not the only particles found in an atom's nucleus. Neutrons, which have no charge, are also found in the nucleus and help to hold the positively charged protons together through the strong nuclear force.
