Answer 2

Step-by-step explanation:

Periodic table of element is organized on the basis of number of protons present in the nucleus of element. Nucleus contain both proton and neutron, whereas, electrons are present in the energy level i.e. outside nucleus so, it is the number of proton which determine the atomic number of an element thereby, it's position on the periodic table.

For example, carbon have six proton and oxygen have eight proton that is why carbon is placed ahead of oxygen in the periodic table.
