When you look at how elements react on the periodic table, you can see some interesting patterns. Here’s a simple breakdown:

1. Metal Reactivity:

   • When you go from left to right across a row on the table, metals usually become less reactive. For example, alkali metals like sodium are very reactive, but transition metals like iron are not as much.

2. Non-metal Reactivity:

   • On the other hand, non-metals get more reactive as you move from left to right. A good example is chlorine; it is much more reactive than the non-metals that are found earlier in the same row.

3. Atomic Radius:

   • As you travel across a row, the atomic size gets smaller. This happens because the positive charge in the nucleus gets stronger, pulling the electrons closer. This change also affects how the elements react.

4. Electronegativity:

   • Electronegativity means how strongly an element attracts electrons when they bond with other elements. This usually gets stronger from left to right, which can change how these elements react with each other.

These patterns show how amazing the periodic table is and how the position of each element affects its behavior!
