If an element X of atomic number Z and mass number Y is…
If an element X of atomic number Z and mass number Y is irradiated by an intense concentration of neutrons, the relevant nuclear equation is
Total atomic number of a product must be = total atomic number of reactants = Z + 0 = Z
Total mass number of a product must be = total mass number of reactants = Y + 1
Now for the right answer to the above question:
- Option A is incorrect. wrong mass number and atomic number of a product.
- Option B is correct. equal total mass and atomic number on both sides.
- C is incorrect. wrong mass number and atomic number of an product.
- D is not the correct answer. Correct mass number, but wrong atomic number.
You may please note these/this:
- Simple addition of all the mass numbers and atomic numbers on both sides must be equal.
