Whakarāpopototia te tuhinga:  He wāhanga matua tēnei o ngā akoranga matū kura mō te neke atu i te kotahi rau tau, engari ināianei ka hiahia pea te ripanga wā ki te whakatakoto anō i muri i te kitenga o ngā pūtaiao i tētahi huānga onge he tino rerekē pea i te mea i whakaarohia i te timatanga. Mo te wā tuatahi ka taea e ngā kairangahau te whakamātautau i te nui o te pūngao e hiahiatia ana hei tango i tētahi irahiko mai i tētahi ngota o te huānga irirangi o te lawrencium. I tēnei wā, kei raro rawa te konganuku onge i te ripanga auau i te pito o tētahi rōpū huānga e mōhiotia ana ko ngā actinides, e noho ana i roto i tētahi poraka motuhake mai i te ripanga matua. Engari ko ngā hua o te rangahau hou e tohu ana he ōrite pea ngā āhuatanga o te huānga ki te konutai me te potassium, tērā pea ka whakakaha i ngā tautohe ka pai ake te whakanoho i roto i te tino tinana o te ripanga auau. Ko te Lawrencium, kua tohua hei Lr i runga i te ripanga auau i runga ake nei, kei roto i tetahi poraka motuhake mai i te teepu matua. Mēnā ka tāruatia anō, ko te tikanga ka ārahi anō pea ngā ākonga matū i te raupapa o te āhua o ngā huānga. Ko te Lawrencium, i kitea tuatahitia i te tau 1961 e te kaipūtaiao karihi a Ernest Lawrence, he tino uaua ki te hanga, ā, he torutoru hēkona noa iho te roa. Nā tēnei i tino uaua ai te ako i te huānga, e taea ana anake te whakaputa i roto i ngā kaiwhakatere ngota. He maha ngā ngota hou kua kitea, kāore i te tīariari i tēnei wā i runga i te ripanga wā. E rua tau ki muri i kii nga kaiputaiao kua kitea te nohoanga o te ngota hou me te tau ngota 115. Ma tenei ka waiho hei tetahi o nga waahanga matū tino taumaha i kitea i tenei ra, kaore hoki e puta noa. Engari i whakahiatohia e nga kaipūtaiao i roto i te taiwhanga mā te whakaeke i tētahi kiriata o tētahi atu huānga taumaha e mōhiotia ana ko te americium ki ngā aniona kārihi. Ko te huānga i puta mai i roto i te wāhanga o te hēkona anake i mua i te waikura ki ngā huānga e kitea nuitia ana. Ahakoa kaore ano kia tapaina he ingoa, kua whakawhiwhia ki a ia te ingoa mo te wa poto o te ununpentium. I kii ano te International Union of Pure and Applied Chemistry i tenei wa kua whakahoutia e iwa tekau ma iwa nga ngota ngota. I roto i te...
Kua ako te Japanese Atomic Energy Agency i te lawrencium mō te wā tuatahi. He tino uaua te hanga o te huānga, ā, e 27 hēkona te hawhe o tōna ora. I kitea e rātau he mea rerekē i ētahi atu huānga hauā kino i roto i te poraka-f. Tērā pea ka whakaoho i te tautohetohe mō te lawrencium kia noho ki te tino wāhanga o te tēpu.
