Answer
Factors which affect metallic and non-metallic character in a periodic table are as follows :
Atomic size — The greater the atomic size, the farther the outermost orbit, and thus lesser is the nuclear pull exerted on it. As a result, electrons can be removed more easily from the valence shell, this making the element more metallic and less non-metallic.
Nuclear charge — The greater the nuclear charge, the greater is the force exerted by the nucleus on the electron of the outermost orbit. This makes it difficult to remove the electron from the outermost orbit. Thus, metallic nature decreases and non-metallic nature increases.
