does reactivity increase down a group for metals

The larger an atom is, the more reactive it will be. Hence, the chemical reactivity of metals increases on going down a group. Thus, these electrons can be lost easily by the element to form positive ions. Why reactivity of metals increase down group?ĭown the group, the effective nuclear charge experienced by valence electrons is decreasing because the outermost electrons are far away from the nucleus. This makes francium the most reactive of the alkali metals. Therefore, the alkali metal with the higher number is more chemically reactive. The outermost electron is held less tightly and escapes more readily. Radius and Reactivity As atomic number increases, so does an atom’s radius. Nonmetals tend to gain electrons in chemical reactions and have a high attraction for electrons within a compound.ĭoes reactivity increase with atomic radius?

Since the ionization energy decreases going down a group (or increases going up a group), the increased ability for metals lower in a group to lose electrons makes them more reactive. Why is the periodic trend for reactivity opposite for metals and non metals? While moving from top to bottom in a group of non- metals, the atomic size increases with the additional number of shells and the force of attraction between the nucleus and valence shell decreases. While moving from top to bottom in a group of the periodic table, the reactivity of non- metals decreases. What is the relationship between reactivity and size for non metals? 6 What is the trend in non metal reactivity down a group?.5 Does reactivity increase as atomic number?.
