Structure of Atom
Isotopes of an element have similar chemical properties and isobars have different chemical properties. Explain.
Isotopes of an element have same number of electrons and protons but have different number of neutrons. Since chemical properties of elements depend upon atomic number, isotopes of an element have similar chemical properties.
On the other hand, isobars have different number of electrons, protons as well as neutrons. Thus, isobars have different chemical properties.
