Stable and Unstable Nuclei 0.0 / 5 ? PhysicsParticle physicsASAQA Created by: akelly_3102Created on: 04-05-18 09:36 What range does the strong nuclear force have? 0.5 fm to 3 fm 1 of 9 What does electromagnetic force affect in the nucleus? It causes all the positively charged protons in the nucleus to repel. 2 of 9 What does gravitational force affect in the nucleus? It causes all of the nucleons in the nucleus to attract each other because of mass 3 of 9 What range does the electromagnetic force act over? Infinite. 4 of 9 Alpha decay happens in what type of atoms? Atoms with more than 62 protons. 5 of 9 What do atoms emit when they undergo alpha decay? An alpha particle. The mass number decreases by 4 and the proton number decreases by 2. 6 of 9 Beta-minus decay happens in what type of atoms? Neutron-rich isotopes. 7 of 9 What do isotopes emit when they undergo beta-minus decay? An electron and an antineutrino. The mass number stays the same but the proton number increases by one. 8 of 9 What type of decay would you expect in a nucleus with 14 nucleons, 6 of which are protons. Explain your answer. Beta-minus decay as the nucleus is neutron rich. 9 of 9
