13.6 In $α$ - decay, there is a loss of 2 protons and 4 neutrons. In every $β +$ decay, there is a loss of 1 proton and a neutrino is emitted from the nucleus. In every $β -$ decay, there is a gain of 1 proton and an antineutrino is emitted from the nucleus.

${}_{88}^{226}{R a}$ $\to$ ${}_{86}^{222}{R n}$ + ${}_{2}^{4}{H e}$

${}_{94}^{242}{P u}$ $\to$ ${}_{92}^{238}U$ + ${}_{2}^{4}{H e}$

${}_{15}^{32}P$ $\to$ ${}_{16}^{32}S$ + $e^{-}$ + $\overset{?}{ν}$

${}_{83}^{210}{B i}$ $\to$ ${}_{84}^{210}{P o}$ + $e^{-}$ + $\overset{?}{ν}$

${}_{6}^{11}C$ $\to$ ${}_{5}^{11}B$ + $e^{+}$ + $ν$

${}_{43}^{97}{T c}$ $\to$ ${}_{42}^{97}{M o}$ + $e^{+}$ + $ν$

${}_{54}^{120}{X e} \to$ ${}_{53}^{120}I$ + $ν$

Find the mass number of an atom whose radius is half of that of a given atom of mass number 192.

Alok Kumar Singh

$r = R_{0} {(192)}^{\frac{1}{3}}$

$\frac{r}{2} = R_{0} {(m)}^{\frac{1}{3}}$

$m = \frac{192}{8} = 24$

A radioactive simple is undergoing a decay. At any time t₁, its activity is A and another time t₂, the activity is $\frac{A}{5} .$  What is the average life time for the sample?

Alok Kumar Singh

$A = A_{0} e^{- λ t_{1}}$ [Radio active decay law]

$\frac{A}{5} = A_{0} e^{- λ (t_{2} - t_{1})}$

$\Rightarrow A v e r a g e l i f e = \frac{1}{λ} = \frac{(t_{2} - t_{1})}{l n 5}$

A sample contains 10^-2kg each of two substances A and B with half lives 4s and 8s respectively. The ration of their atomic weights is 1 : 2. The ratio of the amounts of A and B after16s is $\frac{x}{100}$ . The value of x is ______.

Alok Kumar Singh

$f o r A, t_{\frac{1}{2}} = 4 s e c$

$= m A_{0} e^{-} \frac{0.693}{4} \times 16$

$m_{A} = m_{A 0} e^{- 4 \times 0.693}$ -(1)

for B,

for B, $t_{\frac{1}{2}} = 8 s e c$

$m_{B} = m_{B_{0}} e^{- 2 \times 0.693}$ -(2)

$\frac{m_{A}}{m_{B}} = \frac{m_{A O}}{m_{B O}} \frac{e^{- 4} \times 0.693}{e^{- 2} \times 0.693}$

$\frac{m_{A}}{m_{B}} = \frac{25}{100} = \frac{x}{100} x = 25$
