Change of atomic number and mass number for `alpha` & `beta` decay.

A radioactive element emits 2 alpha -particles and 3 beta -particles . The values of atomic number (Z) and mass number (A) of the new element will be - (A) (A+5), (Z-1) (B) (A-5), (Z+1) (C) (A-8), (Z-1) (D) (A-8), (Z+1)

An alpha particle is released by "_92U^236 Nuclei. The atomic number and mass number of the resultant is

When an alpha - particle is emitted from a uranium nucleus (atomic no. 92, mass number 238), a new nucleus is formed. From this nucleus a beta -particle is also emitted. Wha will be the atomic number and mass number of the final nucleus ?

What are the atomic number and the mass number of the plutonium isotope produced due to two successive beta -decays of the isotope ._92U^239 of uranium ?

Write the complete symbol for : (a) The nucleus with atomic number 56 and mass number 138 , (b) The nucleus with atomic number 26 and mass number 55 , (c) The nucleus with atomic number 4 and mass number 9.

What is the relation between the atomic number (Z) and the mass number (A) of two isobars?

Atoms of the same element having same atomic number but different mass number are called

If alpha = x_1x_2x_3 and beta = y_1y_2y_3 be two three digits numbers , the numbers , the number of pairs of alpha and beta can be formed so that alpha can be subtracted from beta without borrowing is

What do you mean by conservation of mass number and atomic number ? Show that from it two displacement laws of alpha and beta -decay can be obtained from these conservation laws .

For the radioactive nuclei that undergo either alpha or beta decay, which one of the following cannot occur? (A) Isobar of original nucleus if produced (B) Isotope of the original nucleus is produced (C) Nuclei with higher atomic number than that of the original nucleus is produced. (D) Nuclei with lower atomic number than that of the original nucleus is produced.
