I. The trend of decreasing atomic size from left to right within a period is due to the increasing nuclear charge (protons) that attracts the electrons more strongly, making the atomic radius smaller. 
II. Metallic character increases from right to left within a period because as the number of valence electrons increases, the tendency to lose electrons and form positive ions increases, which is a characteristic of metals. 
IV. Group 1 elements (alkali metals) have only one valence electron and therefore have a strong tendency to lose it, while Group 13 elements have three valence electrons and are less likely to lose them. 
V. Ionization potential, which is the energy required to remove an electron from a neutral atom, increases as atomic size decreases because the valence electrons are held more tightly by the increasingly larger nuclear charge. 
III. The statement about basic oxides is not a universal trend and may not consistently hold true for all the elements at the end of each period.
