Question

Write the isotope symbol for each of the following. Z = 11 and A = 23 Z = 28 and A = 64 Z = 80 and A = 201 Z = 74 and A = 186

Answer 1

Case i :-

Z = 11 , A = 23 When Atomic no. of element(Z) = 11 , Atomic weight of element(A) = 23 and element is X then Isotope symbol of element is ₁₁X²³

Case ii :-

Z = 28 , A = 64    When Atomic no. of element(Z) = 28 , Atomic weight of element(A) = 64 and element is X then Isotope symbol of element is ₂₈X⁶⁴

Case iii :-

Z = 80 , A = 201 When Atomic no. of element(Z) = 80 , Atomic weight of element(A) = 201 and element is X then Isotope symbol of element is ₈₀X²⁰¹

Case iv :-

Z = 74 , A = 186   When Atomic no. of element(Z) = 74 , Atomic weight of element(A) = 186 and element is X then Isotope symbol of element is ₇₄X¹⁸⁶
