WebThe reactivity of group 1 elements increases as you go down the group because: the atoms become larger. the outer electron becomes further from the nucleus. Does reactivity increase or decrease? Chemical reactivity of the elements Period – reactivity decreases as you go from left to right across a period . WebJul 12, 2024 · Solubility of the carbonates increases down Group 1. The hydroxides The least soluble hydroxide in Group 1 is lithium hydroxide, but it is still possible to make a solution with a concentration of 12.8 g per 100 g of water at 20°C. The other hydroxides in the group are even more soluble. Solubility of the hydroxides increases down Group 1.

Why does the reactivity increase down group 1 and decrease
WebTrend in reactivity in a group can be explained using the electronic structure of atoms. Looking at the reactions discussed beforehand, when going down group 1 the reactions get more and more vigorous. This suggests that as you go down group 1, the reactivity of the elements increases. WebJun 10, 2008 · Best Answer. Copy. In the alkali metals column (Group 1), atomic radius increases down the group and reactivity increases. There are more shells preventing the attraction between the positive ... WebWhy does reactivity increase down group 1? Click the card to flip 👆 The number of electron shells increases down the group so there is more electron shielding. As a result, there is weaker attraction between the positive nucleus and outer shell electron. This means it is easier to remove an outer shell electron to form a positive metal ion. graduated progressive income tax
