What happens to the reactivity of elements if we move from the left to the right in a period of the periodic table?

As we move from left to right in a period of the periodic table, the reactivity of elements increases.

This is because, as the atomic number increases, the number of electrons in the outermost shell also increases.

The addition of these electrons increases the number of electrons that can be lost during a reaction, making the elements more reactive.

Additionally, the increasing number of protons in the nucleus also causes an increase in the effective nuclear charge, making the outermost electrons more tightly held, and thus more difficult to remove, making them more reactive.

As a result, elements on the right side of the periodic table tend to be more reactive than elements on the left side.
