Identify the nuclide that would be formed from the alpha particle emission of Fm-257.
Elodia [21]

Answer: 1) The nuclide formed from the alpha decay of _{100}^{257}\textrm{Fm} is _{98}^{253}\textrm{Cf}

2) The nuclide formed from the beta-minus decay of _{98}^{253}\textrm{Cf} is _{99}^{253}\textrm{Es}

Explanation:

1) For alpha-decay

In this process, alpha particle is released.

Equation follows:

_{100}^{257}\textrm{Fm}\rightarrow _{98}^{253}\textrm{Cf}+_2^4\alpha

The nuclide formed is _{98}^{253}\textrm{Cf}

2) For beta-minus decay

In this process, a neutron is converted into a proton and an electron.

Equation follows:

_{98}^{253}\textrm{Cf}\rightarrow _{99}^{253}\textrm{Es}+_{-1}^0\beta

The nuclide formed is _{99}^{253}\textrm{Es}
