Helion (chemistry)

In chemistry, there is a tiny part of an atom called a proton that is positively charged and a tiny part called an electron that is negatively charged. When an atom loses one or more electrons, it becomes positive because there are more protons than electrons. When an atom gains one or more electrons, it becomes negative because there are more electrons than protons.

Now, Helion is the nucleus of a hydrogen atom which has lost one of its electrons. This means that it has only one proton, which is positively charged and no electrons, making it positively charged as well. A hydrogen atom with an electron is called a proton or hydrogen ion, while a hydrogen atom with no electrons is called a helion.

Because helion has a positive charge, it can easily attract negatively charged particles like electrons. This can lead to chemical reactions where a helion will react with another molecule to steal an electron. For example, in the process of making water, two hydrogen ions, or helions, combine with an oxygen atom to form water molecules.

In summary, helion is the nucleus of a hydrogen atom that has lost its electron, giving it a positive charge. Because of its positive charge, it can easily attract negatively charged particles and participate in chemical reactions.
