Neutrons are important because they help determine the number of protons in an atomic nucleus. An atom of iron, for example, is represented by 5726fe. This means that there are 26 protons and 30 neutrons in the nucleus. The number of neutrons and protons determine the type of atom. Some atoms have more than one nucleus, which is called a compound. For example, water can be represented as HOHO or with two hydrogen nuclei (H) and one oxygen nucleus (O). The total number of protons in all three nucleuses equals 18; however there are no neutrons to speak of because they only exist in atomic nucleii where they help balance out the charges caused by an unequal number of electrons on opposite sides of the nucleus. A neutron’s role is not limited to balancing proton charges–it also helps regulate nuclear reactions like fission and fusion that power stars including our own sun. Neutron-less matter would look
