How does the position of an element in the periodic table relate to its properties?

The position of an element in the periodic table is crucial in determining its properties. Elements in the same group have similar chemical properties due to the same number of valence electrons, while elements in the same period have the same number of electron shells, impacting their atomic size and reactivity. Additionally, the position of an element can also reveal its metallic or non-metallic properties. For example, elements on the left side of the periodic table tend to be metals, while those on the right side are non-metals. This systematic arrangement allows for predictions about an element's behavior and characteristics based on its position in the table.
