The reactivity of most nonmetals shows a trend that generally **increases from left to right across the periodic table**, excluding the noble gases. This is primarily due to the increasing electronegativity and the effective nuclear charge as you move across a period, making nonmetals more eager to gain electrons and react, especially in forming compounds. Exceptions do exist, but this is a general trend observed for many nonmetals.
