Solution:

On moving along a period, the tendency to lose electrons decreases and thus, the metallic character decreases. Since, the oxides of non-metals are acidic. Thus, it can be said, along a period from left to right basic character decreases while on moving downward, basic character increases due to increase in metallic character.
