Isobars Explanation:
- Definition: Isobars are atoms of different elements that have the same mass number but different atomic numbers.
- Example: In this case, atoms X and Y have a mass number of 40 each, but their atomic numbers are different (20 and 18). This makes them isobars.
- Comparison: Isotopes are atoms of the same element with the same atomic number but different mass numbers. Solid and liquid refer to physical states of matter, which is not relevant in this context. Chemically similar atoms would have the same atomic number and similar chemical properties, which is not the case here.
- Conclusion: Therefore, based on the given information, X and Y are examples of isobars as they have the same mass number but different atomic numbers.

Elements with atomic number 18 and 20 are Argon and potassium respectively.
Isobar compounds have the same mass number but the different atomic number and chemical properties depend upon the number of electrons so isobars have different chemical properties.
