Trend in reactivity of group 2
WebEach row on the periodic table represents a new energy level/electron shell. So as you go down the group there are more energy levels, increasing the atomic radius. The first electron to react will be on the outer shell. The reactivity increases down the group from Mg to Ba. WebGroup 2 Trends. Berylium, magnesium, calcium and barium are a few examples of group 2 elements. All group 2 elements have two electrons in their outermost shell which allows them to exhibit similar chemical properties. Atomic Radius. Atomic radius increases down group 2. Although all atoms in group 2 have two electrons in their outer shell ...
Trend in reactivity of group 2
Did you know?
WebAs group 2 in the periodic table comprises of metals, the reactivity of group 2 elements towards chlorine increases when working our way down the group 2 metals. This is compared to non-metals when the reactivity decreases working down a non-metal group such as group 7. WebDescribe and explain the trend in reactivity of the Group 2 elements with dilute hydrochloric acid as the group is descended (5) - As Group 2 is descended reactivity increases - This is because atomic radii increase (more shells) - This creates more shielding from attractive force of nucleus
Webbeing only sparingly soluble. The pH of the Group 2 hydroxide solution is pH 10-12. 1.3.2 (b) Reactivity of Group 2 Elements. The overall trend, for the reactivity of Group 2 metals with water, is an increase down the group. The outer electrons are easier to remove as they are further from the nucleus and there is more shielding resulting in WebGroup 2 is a group of metals in the periodic table.

Web1.3.2 - Group 2. (a) describe the redox reactions of the Group 2 elements Mg - Ba: Group 2 elements react vigorously with oxygen. A redox reaction occurs where an ionic oxide is produced with the formula MO (where M is the group 2 metal) The oxidation number of calcium changes from 0 in 2Ca to +2 in 2CaO, this is an oxidation.

Small highly charged positive ions distort the electron cloud of the anion. The larger the anion the easier the distortion, as seen with the carbonate ion. Hence polarising ability of the M 2+ ion decreases down the group. chopard geneve diamond watchWebTrends in Group 2 Compounds. Group 2 Elements are called Alkali Earth Metals.
