The bombardment of nitrogen with alpha particles will produce______________?
Correct answer: B. Proton
- A. Neutron
- B. Proton
- C. Electron
- D. Positron
Explanation
When nitrogen-14 is bombarded with an alpha particle, the reaction can be written as 14N + 4He -> 17O + 1H, so a proton is emitted. The likely mistake is choosing a neutron because nuclear reactions often involve neutron emission, but this particular reaction conserves mass number and charge by producing a proton.

About Composition of Atomic Nuclei
Atomic nuclei contain positively charged protons and electrically neutral neutrons, collectively called nucleons. Questions use atomic number, mass number and nuclear notation to identify isotopes, isobars and isotones, and may connect nuclear composition with nuclear charge, mass defect, binding energy and the stability of the nucleus.
