Such atoms which have same mass no. bit different atomic no. are called isobars.
No, it is not neceasary for them to have same chemical properties becoz chemical properties depend upon the no. of electrons (or the no. of protons) ,i.e. on atomic no.

Te atoms belongs to atomic number 18 is Argon and 20 Potassium.
Term use to relate them is Isobar.
Isobar refer to those atoms who have same mass number but different atomic number.
No, they don't have same chemical property because chemical property depend upon number of electron so isobar have different chemical property.
