Question

1.)You are conducting an investigation in your lab involving radioactive isotopes. You notice that the daughter produced is immediately adjacent (next) to the parent on

the periodic table. What type of decay could be happening. Explain.

2.)Determine the binding energy, in Joules, of a single atom 197(top) 79(bottom)  Au which has a mass of 196.966569 u .

3.)Dr.S is nearsighted and has a lenses with a power of -6.25 Diopters. What type of lens is this? What is the focal length of the lens? What is the far-point for Dr.S when viewing a distant object?

Answer 1

Explanation :

You are conducting an investigation in your lab involving radioactive isotopes. You notice that the daughter produced is immediately adjacent (next) to the parent on the periodic table. The decay is minus beta decay.

In this type of decay, a neutron dissociates into a proton and an electron. The by products are antineutrino and electron.

For example,

The minus beta decay of carbon gives the nitrogen along with antineutrino and an electron. Nitrogen in this case, is daughter nuclei and carbon is parent. Also, nitrogen lies adjacent to carbon.
