Did you know?
WebSep 3, 2024 · The most reactive element is fluorine, the first element in the halogen group. The least reactive metal is platinum, followed by gold. Because of their low reactivity, … 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.
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. WebAs 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 …
WebA standard reaction expressing the reactivity of metals with acids is given below- M + 2HCl → MCl2 + H2 Acting as a reducing agent Alkaline earth metals, like alkali metals, are powerful reducing agents. This is shown because their reduction potentials have substantial negative values. WebEach hydrogen atom has one valence electron and is univalent. In chemistry and physics, a valence electron is an electron in the outer shell associated with an atom, and that can participate in the formation of a chemical bond if the outer shell is not closed. In a single covalent bond, a shared pair forms with both atoms in the bond each ...
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
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. Calcium hydroxide is mainly formed as a white precipitate (although some does dissolve). incident handler salary cyber securityWebAug 15, 2024 · All of Group 1 elements —lithium, sodium, potassium, rubidium and cesium react vigorously or even explosively with cold water. In each case, the aqueous metal hydroxide and hydrogen gas are produced, as shown: (1) 2 X ( s) + 2 H 2 O ( l) → 2 X O H ( a q) + H 2 ( g) where X is any Group 1 metal. In each of the following descriptions, a very ... inbody portalWebAs we go down a group the reactivity of non-metals decrease. This is because : The number of valence shells increases.
