The unstable nucleus 82212Pb decays with β-particle emission, having a half-life of 10 h. From this it follows that theA : mass number of the product is 212B : atomic number of the product is 81C : fraction of the original isotope remaining after 20 h is 14D : product nucleus formed belongs to same groupSelect the correct alternate.
