1 00:00:00,000 --> 00:00:00,690 2 00:00:00,690 --> 00:00:03,660 Allt vi har gjort så här långt 3 00:00:03,660 --> 00:00:06,410 inom kemin har handlat om stabiliteten hos 4 00:00:06,410 --> 00:00:08,420 elektroner och att elektroner helst 5 00:00:08,420 --> 00:00:10,340 befinner sig i stabila skal. 6 00:00:10,340 --> 00:00:14,030 Och som med allt annat, om man utforskat atomen 7 00:00:14,030 --> 00:00:16,400 lite djupare inser man att elektroner inte är de 8 00:00:16,400 --> 00:00:19,250 enda sakerna som finns och påverkar en atom. 9 00:00:19,250 --> 00:00:24,250 Atomkärnan själv kan växelverka och ha 10 00:00:24,250 --> 00:00:27,140 en viss instabilitet, som kan ses i vissa försök. 11 00:00:27,140 --> 00:00:28,740 Det är det vi ska titta närmare på 12 00:00:28,740 --> 00:00:31,420 i denna video. 13 00:00:31,420 --> 00:00:35,110 Att förklara företeelserna från grunder är allt för avancerat 14 00:00:35,110 --> 00:00:37,450 för en grundkurs i kemi, men det är i alla fall 15 00:00:37,450 --> 00:00:39,570 bra att veta att saker händer. 16 00:00:39,570 --> 00:00:43,110 17 00:00:43,110 --> 00:00:45,570 18 00:00:45,570 --> 00:00:49,280 19 00:00:49,280 --> 00:00:52,810
