Question

The symbol for a radioactive nuclide is 234/90

Answer 1

A is your answer, "The atomic number of the radioactive nuclide is 90".

Answer 2

Answer: The correct answer is the atomic number of the radioactive nuclide is 90.

Step-by-step explanation:

The general representation of a radioactive nuclei is given as:
`_Z^A\textrm{X}`

Where,

Z = Atomic number of the nuclide

A = Atomic mass of the nuclide

X = Symbol of the nuclide

We are given:

Representation of radioactive nuclei =
`_(90)^(234)\textrm{Th}`

Atomic number of the given nuclide is 90, atomic mass of the given nuclide is 234 and the symbol of the nuclide is 'Th'

Hence, the correct answer is the atomic number of the radioactive nuclide is 90.
