Which of the following pair of nuclides are Isobars? |
${}_1^2H,{}_1^3H$ ${}_1^3H,{}_1^2H$ ${}_{80}^{198}Hg,{}_{79}^{197}Au$ ${}_1^1H,{}_1^3H$ |
${}_{80}^{198}Hg,{}_{79}^{197}Au$ |
The correct answer is Option (3) → ${}_{80}^{198}Hg,{}_{79}^{197}Au$ Isobars have the same mass numbers (198) but different atomic numbers, so they are isobars. $∴{}_{80}^{198}Hg,{}_{79}^{197}Au$ |
