QuestionWhich statement is false about the atoms $^{13} \mathrm{~N}, \,^{14} \mathrm{~N}, \,^{15} \mathrm{~N}$?

Studdy Solution
Finally, let's check the mass numbers. The mass numbers for ${ }^{13} \mathrm{~},{ }^{14} \mathrm{~}$, and ${ }^{15} \mathrm{~}$ are13,14, and15 respectively. This means they do not all have the same mass number.
So, the statement "They all have the same mass number" is not true for the atoms ${ }^{13} \mathrm{~},{ }^{14} \mathrm{~}$, and ${ }^{15} \mathrm{~}$.
