What are isotopes?

Given there are $$3$$ isotopes of hydrogen $$(^{1}H, ^{2}H$$ and $$^{3}H$$) and $$2$$ isotopes of oxygen $$(^{15}O$$ and $$^{16}O)$$, how many peaks would be expected on a mass spectrum for the hydronium ion, $$H_{3}O^{+}$$?

Watermelon model of atom was proposed by:

If $$E_P$$ and $$E_k$$ represent potential energy and kinetic energy respectively, of an orbital electron, then according to Bohr's theory:

Rutherford model could not explain:
