Aradioactive nuclide that is used to label blood platelets has 49 protons and 62 neutrons. which is the symbol of this nuclide?

The nuclide is

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 = where, X = element

A = Atomic mass

Z = Atomic number

Radioactive isotope used to label blood platelets is

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
