swansont Posted December 22, 2019 Share Posted December 22, 2019 How many protons are in Am? Link to comment Share on other sites More sharing options...
Rachel Maddiee Posted December 23, 2019 Author Share Posted December 23, 2019 95 protons Link to comment Share on other sites More sharing options...
swansont Posted December 23, 2019 Share Posted December 23, 2019 5 hours ago, Rachel Maddiee said: 95 protons And you wrote "243/93 Am" which is the mistake people were hinting about. Z didn't change in the reaction, but it must decrease by 2 in alpha decay Link to comment Share on other sites More sharing options...
