Question

Supply the missing information in the following table:

Short answer

Required table is :

Medical use	Atomic number	Mass number	Number of protons	Number of neutrons
Heart imaging	${}_{81}{}^{201}\mathrm{Tl}$	$201$	$81$	$120$
Radiation therapy	${}_{27}{}^{60}\mathrm{Co}$	$60$	$27$	$33$
Abdominal scan	${}_{31}{}^{67}\mathrm{Ga}$	$67$	$31$	$36$
Hyperthyroidism	${}_{53}{}^{131}\mathrm{I}$	$131$	$53$	$78$
Leukemia treatment	${}_{15}{}^{32}\mathrm{P}$	$32$	$15$	$17$

Step-by-step solution

Given information

We are given a table to complete.

Medical use	Atomic symbol	Mass number	Number of protons	Number of neutrons
Heart imaging	${}_{81}{}^{201}\mathrm{Tl}$
Radiation therapy		$60$	$27$
Abdominal scan			$31$	$36$
Hyperthyroidism	${}_{53}{}^{131}\mathrm{I}$
Leukemia treatment		$32$		$17$

Simplify

As we know the symbol ${}_{\mathrm{z}}{}^{\mathrm{y}}\mathrm{X}$represents :

X= atom

Y= mass number

Z= number of proton

Y-Z= number of neutrons

Therefore,

Required table with all data is :

Medical use	Atomic symbol	Mass number	Number of protons	Number of neutrons
Heart imaging	${}_{81}{}^{201}\mathrm{Tl}$	$201$	$81$	120
Radiation therapy	${}_{27}{}^{60}\mathrm{Co}$	$60$	$27$	$33$
Abdominal scan	${}_{31}{}^{67}\mathrm{Ga}$	$67$	$31$	$36$
Hyperthyroidism	${}_{53}{}^{131}\mathrm{I}$	$131$	$53$	$78$
Leukemia treatment	${}_{15}{}^{32}\mathrm{P}$	$32$	$15$	$17$
