What are the limitations of Rutherford's model of the atom?

For the following statements,write $T$ for True and $F$ for False.
$(a)$ $J$.$J$. Thomson proposed that the nucleus of an atom contains only nucleons.
$(b)$ $A$ neutron is formed by an electron and a proton combining together. Therefore,it is neutral.
$(c)$ The mass of an electron is about $\frac{1}{2000}$ times that of a proton.
$(d)$ An isotope of iodine is used for making tincture iodine,which is used as a medicine.

Summarize the rules for writing the distribution of electrons in various shells for the first eighteen elements.

Write the electronic configuration of any one pair of isotopes and isobars.

If $K$ and $L$ shells of an atom are full,then what would be the total number of electrons in the atom?

Compare all the proposed models of an atom given in this chapter.
