Isotopes, isobars and isotones

The chemical properties of different isotopes of an element are almost the same.

Isobars are atoms (nuclides) having same atomic mass number but the different atomic number.

Isotopes that emits radiation are called _____. (radioisotope / stable isotope)

What are isotones? Give example.

Why isobars have different chemical properties?
