Atoms And Nuclei Question 362

Question: A radioactive nucleus undergoes a series of decay according to the scheme $A \overset{a}{\to} A_{1} \overset{β}{\to} A_{2} \overset{α}{\to} A_{3} \overset{γ}{\to} A_{4}$ If the mass number and atomic number of ‘A’ are 180 and 72 respectively, then what are these numbers for $A_{4}$

Options:

A) 172 and 69

B) 174 and 70

C) 176 and 69

D) 176 and 70

Show Answer

Answer:

Correct Answer: A

Solution:

$_{72} A^{180}$

$\overset{α_{70}}{\to}$

$A_{1}^{176}$

$\overset{β_{71}}{\to}$

$A_{2}^{176}$

$ {{\xrightarrow{\alpha }}{69}}A{3}^{172}{{\xrightarrow{\gamma }}{69}}A{4}^{172} $
