Isotopes are atoms of the same element with the same number of protons but different numbers of neutrons. Radioactive isotopes are unstable isotopes. Atomic number (Z) = number of protons. Mass number (A) = number of protons + number of neutrons.
Match List-I with List-II. List-I List-II (i) Equal to the number of (a) Radioactive isoprotons found in the nucletopes us (ii) Equal to the number of (b) Radiation unit protons and neutrons in the nucleus (c) Atomic number of a chemical ele‐ (iii) ¹H, ³²S, ¹²C, ¹²⁷I, ⁵⁹Co ment (d) Mass number (iv) Curie (Ci), Millicurie of a chemical ele‐ (mCi) ment (v) ³H, ³⁵S, ¹⁴C, ¹³¹I, ⁶⁰Co Choose the correct answer from the options given below :
