The particle A is converted into C via the following reaction. A → B + 2 H e 4 B → C + 2 e - Then

Options

  1. AA and C are isobars
  2. BA and C are isotopes
  3. CA and B are isobars
  4. DA and B are isotopes

Correct answer

B. A and C are isotopes

Step-by-step solution

Let x be the mass number of A and y the atomic number. Then , since atomic number and mass number remain conserved, we have y A x → y - 2 B x - 4 + 2 H e 4 y - 2 B x - 4 → y C x - 4 + 2 - 1 e 0 Hence, we observe that A and C are isotopes as their atomic numbers are same but mass numbers are different.
