What are isobars? Give one example.
(N/A) Isobars are atoms of different elements that have the same mass number but different atomic numbers.
For example,${ }_{18}^{40} Ar$ and ${ }_{19}^{40} K$ are isobars because both have a mass number of $40$ but different atomic numbers ($18$ and $19$ respectively).
