Qhov kev tshawb pom ntawm cov proton tau lees paub rau Ernest Rutherford Ernest Rutherford Rutherford tau tig rov qab Thomson tus qauv hauv xyoo 1911 nrog nws qhov kev paub zoo ntawm cov ntawv ci kub uas nws tau pom tias lub atom muaj lub hauv paus me me thiab hnyav. Rutherford tau tsim ib qho kev sim siv cov alpha hais tawm los ntawm cov khoom siv hluav taws xob los ua kev soj ntsuam rau lub ntiaj teb tsis pom ntawm cov qauv atomic. https://en.wikipedia.org › wiki › Rutherford_model
