WebJan 7, 2024 · Reactivity increases down the group. This is because the outer electron in each atom is further away from the nucleus as you go down the group and so the electrostatic forces between the nucleus and the outer electron are weaker. Subsequently, one may also ask, what is the trend in reactivity in Group 1 with water? WebJun 27, 2024 · The reactivity of Group 7 elements decreases down the group. The electrons in the outer shell move further away from the nucleus as we go down the group and the attraction force between the electrons and the nucleus become weaker and weaker. This weaker attraction in the larger atoms makes it harder to gain electron.

WebJul 12, 2024 · The densities of the Group 1 elements increase down the group (except for a downward fluctuation at potassium). This trend is shown in the figure below: The metals in this series are relatively light— lithium, sodium, and potassium are less dense than water (less than 1 g cm -3 ). 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. speech therapist in cape may court house nj
