In nuclear reaction, 7N14 + 2He4 -> 8O17+_ the missing particle is:
Correct answer: A. Proton
- A. Proton
- B. alpha-particle
- C. Electron
- D. Position
- E. Neutron
Explanation
Adding the atomic numbers on reactant side the answer should be 9. Since oxygen has atomic number 8. it means that another element having atomic number 1 should also be formed to balance the equation. Similarly the reaction between the above reactants should produce a product having mass number of 18 but an Oxygen atom of mass number 17 leaeves room for another atom having mass number 1. In conclusion, the missing particle has an atomic number and mass number 1 which is a Hydrogen Atom 11H also simply known as a proton.
