1.Describe what happens to a carbon-11 atom when it undergoes positron emission. The decay of a carbon-11 atom _____(options;changes a nuetron into proton, changes proton into neutron, is hit with a neutron, reconfigures its protons and neutrons) and this causes it to emit______(options; a negatively charged electron sized particle, a positively charged electron sized partticle, two atoms and several neutrons, two neutrons and two protons) 2.An atom undergoes radioactive decay according to this equation: ___. What is the identity of...

Activity 27-7. Nuclear decays II [Accompanies Section 27-6] (a) Rank the following decays in order of the change in atomic number Z that occurs in the decaying nucleus, from most positive (greatest increase in Z) to most negative (greatest decrease in Z). If any two decays cause the same change in Z, state this. Explain how you made your ranking. (i) Alpha decay (emission of a He nucleus of charge +2e) (ii) Beta-minus decay (emission of an electron of charge...
A nucleus whose mass is 3.730032 x 10-25 kg undergoes spontaneous "alpha" decay. The original nucleus disappears and there appear two new particles: a He-4 nucleus of mass 6.640678x10-27 kg (an "alpha particle" consisting of two protons and two neutrons) and a new nucleus of mass 3.663533 x 10-25 kg (note that the new nucleus has less mass than the original nucleus, and it has two fewer protons and two fewer neutrons). In these calculations, it is very important to...
thank u so much! 6. One form of nuclear radiation, beta decay, occurs when a neutron changes into a proton, an electron, and a neutral particle called an antineutrino: n → pt + e + De, where ve is the symbol for an antineutrino. When this change happens to a neutron within the nucleus of an atom, the proton remains behind in the nucleus while the electron and neutrino are ejected from the nucleus. The ejected electron is called a...

Breaking radiation E. None of the above 14. What is "chain reaction" of nuclear reactions? A. the joining together of protons and neutrons to form atomic nuclei continuously B. the joining together of light nuclei to form heavy ones continuously C. the successive fissions of heavy nuclei induced by neutrons...
