Answer: The nuclide is
$_(49)^(111)\textrm{In}$

Explanation: We are given a radioactive nuclide having 46 protons and 62 neutrons.

In an element,

Atomic number = number of protons = number of electrons

Hence, Atomic number = 49

and, Atomic mass = number of neutrons + number of protons

Atomic mass = 62 + 49 = 111

An element having atomic number 49 is Indium (In).

Representing an element =
$_(Z)^(A)\textrm{X}$ where, X = element

A = Atomic mass

Z = Atomic number

Radioactive isotope used to label blood platelets is
$_(49)^(111)\textrm{In}$
