Answer to Problem 95A

The two complete nuclear reaction is as follows:

  109270Mt107266Bh+24He

  107266Bh105262Db+24He

Explanation of Solution

According to nuclear reactions, the sum of the atomic number and mass number on the reactant side is equal to the sum of the atomic number and mass on the product side.

Element 107 Bh is formed when nuclei of element 109 Mt each emit an alpha particle.

Let m and n be the mass number of element 107 and element 109 respectively.

  109mMt107nBh+24He   ...... (1)

Nuclei of element 107 each emit an alpha particle forming an atom with a mass number of 262.

Let Y be element formed from element 107 and x be its atomic number.

  107nBhx262Y+24He   ...... (2)

Equate the values of the atomic number of the reactants and products.

  107=x+2x=1072x=105

Equate the values of the mass number of the reactants and products.

  n=262+4n=266

The element with atomic number 105 is Dubnium.

The equation (2) is rewritten after the substitution of values.

  107266Bh105262Db+24He

The equation (1) is rewritten after the substitution of values.

  109mMt107266Bh+24He   ...... (3)

Equate the values of mass number of the reactants and products.

  m=266+4m=270

The equation (3) is rewritten after the substitution of values.

  109270Mt107266Bh+24He
