The symbol for a radioactive nuclide is 210/84 Po. which statement is correct

Answer is: The number of neutrons present in the nucleus of each atom is 126.

Polonium (Po) has atomic number 84. Atomic number (Z) is the number of protons, which is characteristic of a chemical element.

Z = p⁺ = 84.

A = p⁺ + n°; mass number is the total number of protons and neutrons in a nucleus.

A = 210.

n° = 210 - 84.

n° = 126; number of neutrons.

The number of neutrons present in the nucleus of each atom is 126.
