if I'm correct do mark my answer as brainliest
This is due to the phenomenon known as the Inert pair effect.
Orbitals shield better with a lower azimuthal quantum number(l). Hence, s orbitals shield better than p which shields better than d which is better than f, etc.
The electronic configuration of Si is [Ne] 3s²3p². The 2s and 2p orbitals are shielding the electrons from the nucleus. So the s and p electrons are ready to be ionized. And hence shows a +4 oxidation state.
Similarly, as we move down the group, atomic size increases, and metallic character also increases. Also, lead is below Si and a lower oxidation state is more stable down the group. Hence lead shows a +2 oxidation state.

Here, we found this answer my looking at the key words 'naturally occurring isotopes'
An isotope is a different amount of neutrons, making the atomic mass change.
