- Select the pairs of isobars from the following nuclei : $^{12}_{6}\text{Na}^{23}$, $^{12} _{6}\text{Mg}^{24}$, $^{11}_{5}\text{Na}^{24}$ - $^{12}_{6}\text{Mg}^{24}$, $^{11} _{5}\text{Na}^{24}$ - $^{12}_{6}\text{Na} ^{23}$, $^{12}_{6}\text{Mg}^{24}$ - $^{12} _{6}\text{Na}^{23}$, $^{11}_{5}\text{Na}^{24}$
- Select the pairs of isobars from the following nuclei : $$_{12}Na^{23}, _{12}Mg^{24}, _{11} Na^{24}$$
- Select the pairs of isobars from the following nuclei : ${ }_{12}^{25} \mathrm{Na},{ }_{12} ^{24} \mathrm{Mg},{ }_{11}^{24} \mathrm{Na} $ - ${ }_{12} \mathrm{Mg}^{24},{ }_{11} \mathrm{Na}^{24}$ - ${ }_{12} \mathrm{Na}^{23},{ } _{12} \mathrm{Mg}^{24}$ - ${ }_{12} \mathrm{Na}^{23},{ }_{11} \mathrm{Na}^{24}$
- Both have the same atomic number (12) but different mass numbers (25 and 24). These would be isotopes of an element with Z=12. They are not isobars.- Option C: ${ }_{12}^{25} \mathrm{Na}$ and ${ }_{11}^{24} \mathrm{Na} $. - ${ }_{12}^{25} \mathrm{Na}$: Mass number (A) = 25, Atomic number (Z) = 12. - ${ }_{11} ^{24} \mathrm{Na}$: Mass number (A) = 24, Atomic number (Z) = 11. They have different mass numbers and different atomic numbers. They are neither isobars nor isotopes.Therefore, option A correctly identifies a pair of isobars. 35. The ratio of momenta of an electron and an $\alpha$-particle which are accelerated from the rest by a potential difference of 100 volt is (m$_e$ – mass of electron, m$_\alpha$ – mass of $\alpha$-particle)
