WebThe reactivity of an element belonging to metals increase on moving from top to bottom in a group of the periodic table. While moving from top to bottom in a group of metals in the periodic table, the atomic size increases with the increment in the number of shells and the force of attraction between the nucleus and valence shell decrease. WebAug 15, 2024 · The equation for the reactions of any of these metals would is as follows: (4) X ( s) + 2 H 2 O ( l) + X ( O H) → X ( O H) 2 ( a q o r s) + H 2 ( g) The hydroxide solubilities increase down the group.

As we go down the group, the atom gets bigger. The bigger the atom, the further away the last electron. Therefore, the attraction between the nucleus and the last electron gets weaker. This makes it easier for the atom to give up the electron which increases its reactivity. inbox telus webmail

WebAll group 1 metals have one electron in its outer shell. As we go down the group, the atom gets bigger. The bigger the atom, the further away the last electron. Therefore, the attraction between the nucleus and the last electron gets weaker. This makes it easier for the atom to give up the electron which increases its reactivity. WebSolution As we go down a group the reactivity of non-metals decrease. This is because : The number of valence shells increases The force with which the nucleus holds the electrons decreases Thus the tendency to lose electrons increases Since non metals gain electrons to form a completely filled outermost shell,the reactivity decreases
