23Ne has a neutron to proton ratio that places it above the belt of stability. What is the most likely form of decay for 23Ne? a) Alpha decay b) Electron capture c) Positron emission d) Beta decay e) Electron capture OR positron emission Polonium-212 is converted into lead-208 by __________ emission. a) alpha b) positron c) beta d) electron capture e) gamma
If a nucleus has a neutron-proton ratio below the belt of stability, what type of decay is it likely to undergo?
5) An isotope with atomic number > 83, which lies close to the band of stability, will generally decay through α decay. β decay. γ decay. positron decay. electron capture.
Which of the following statements in regarding radiation is true? a)When α-decay occurs, the atomic mass will decrease but the element will stay the same. b)Neutrinos have a charge equal to zero and have very little mass; they are detected in α-radiation c)Electrons edited in β-decay are not orbital electrons , rather produced within the nucleus from a neutron changing into a proton. d)?-ray carries a positive charge and may occur from a violent collision with another particle.
Please help, I thought it was true because the Neutron to Proton
ratio is 1. Maybe I'm missing something. Please help and thank
you.
