Chapter SH, Problem 20.7APP

To determine

To calculate: Number of beta particles emitted.

Answer to Problem 20.7APP

Number of beta particles emitted is 1.

Explanation of Solution

Given:

  $\text{K}$ decays to $\text{C}\text{a}$ .

Calculation:

  $\text{K}$ loses a beta particle as follows:

  $\text{K}\to \text{C}\text{a + }{\beta }^{-}$

A neutron changes to a proton. Hence the atomic number increases by 1.

Therefore, only one beta particle is emitted.

Conclusion:

Number of beta particles emitted is 1.
