An isotope has the same nnumber of protons (atomic number), but a different nucleon number (mass number). 2 of 19 what is above the element (number wise)? mass number (nucleon number) which is protons and neutrons. 3 of 19 what is below the element (number wise)? the atomic (proton) number. 4 of 19 what is specific charge? particle charge/mass. (CKg-1) 5 of 19 what is the charge of a single nucleon? 1.6X10-19 C 6 of 19 what is the mass of a single nucleon? 1.67X10-27 Kg 7 of 19 what is the charge on a proton? positive. 8 of 19 what is the charge of a neutron? neutral. 9 of 19 What is the charge of an electron? negative. 10 of 19 when finding the charge of a nucleon what do you multiply it by? the proton number. 11 of 19 when finding the mass of a nucleon what do you multiply it by? the mass number. 12 of 19 what are the 4 forces in the universe? Gravity, Electromagnetic, Strong nuclear and weak nuclear. 13 of 19 what does the nuclear strong froce overcome? the electromagnetic repulsion force between protons. 14 of 19 what is the attractive range between protons? 0.5-4fm (5X10-16m - 4X10-15m) 15 of 19 What does an alpha particle consist of? 2 protons + 2 neutrons. 16 of 19 what does the element lose through alpha decay? 2 protons + 2 neutrons. 17 of 19 What happens in beta-minus decay? One neutron turns into a proton and an electron, this is electron leaves the atom. 18 of 19 what happens to the element numbers after beta-minus decay? you add one to the bottom number (atomic number 19 of 19
