Vedclass · Answer

(B) Isotopes are atoms of the same element that have the same atomic number but different mass numbers.In the given representations:$A = { }_{17}^{35} A$ (Atomic number $Z = 17$,Mass number $A = 35$)$B = { }_{20}^{40} B$ (Atomic number $Z = 20$,Mass number $A = 40$)$C = { }_{17}^{37} C$ (Atomic number $Z = 17$,Mass number $A = 37$)$D = { }_{19}^{38} D$ (Atomic number $Z = 19$,Mass number $A = 38$)Since $A$ and $C$ both have the same atomic number $(Z = 17)$ but different mass numbers ($35$ and $37$),they are isotopes.

Identify the isotopes out of $A, B, C$ and $D$ given the following representations:
${ }_{17}^{35} A, { }_{20}^{40} B, { }_{17}^{37} C, { }_{19}^{38} D$
