The properties of elements gradually change across any period of the periodic table. This is due to the increase in atomic number and changes in electron configuration. In general, elements become less metallic and more non-metallic as one moves from left to right across a period. Additionally, the size of the elements decreases as the atomic number increases, due to the increasing nuclear charge pulling the electrons closer to the nucleus.
