The centre of an atom. Except for the hydrogen atom, the nucleus is made up of protons and neutrons (the hydrogen atom has only one proton and no neutrons). Electrons move around the nucleus of an atom. An atom contains the same number of electrons as the number of protons in the nucleus and therefore has a neutral charge.

Ko Tā Ernest Rutherford o Aotearoa te tohunga pūtaiao tuatahi o te ao ki te whakaputa kōrero mō te karihi. I kite  tuatahi ia i te mahi a te karihi i tētahi o ana whakamātautau i te tau 1911.  Mai i taua wā, kua whanake haere te mātauranga e pā ana ki te karihi. Ināianei, e whakamahia  ana tēnei mātauranga ki te whakaputa pūngao karihi, ki te hanga hoki i te pahū karihi. Kāore e ārikarika te tukunga o te pūngao i te tauhohe karihi.
