periodic table effects

Periodic table effects refer to how elements behave and interact based on their position. For example, as you move across a row (period), elements tend to gain electrons and become less metallic. Moving down a column (group), elements usually have larger atoms with more electron shells, making them more reactive if metallic or less reactive if non-metallic. These effects influence properties like reactivity, state (solid, liquid, gas), and how elements bond. Understanding these patterns helps predict how elements will behave in chemical reactions without needing detailed experiments for each one.
