WHAKAMĀRAMA

Ko te pokapū o tētahi ngota. He iraoho, he iramoe hoki kei te karihi, hāunga te ngota hauwai - kotahi anake tōna iraoho, kāore ōna iramoe. He irahiko e rere āwhio haere ana i te karihi. He ōrite te maha o ngā irahiko me te maha o ngā iraoho o tētahi ngota, nō reira kāore he whana hiko o te ngota.

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.
