WebAug 18, 2024 · Four major factors affect reactivity of metals: nuclear charge, atomic radius, shielding effect and sublevel arrangement (of electrons). Metal reactivity relates to ability … WebAg, Au, Pt, Hg. The most active metals are so reactive that they readily combine with the O 2 and H 2 O vapor in the atmosphere and are therefore stored under an inert liquid, such as mineral oil. These metals are found …

Why does reactivity decrease down a group? - Daily Justnow
WebReactivity is dependent on the classification of an element (metals and non-metals), as they both have differing periodic trends. The reactivity of metals increases further left along a period, and further down a group. On the other hand, reactivity in non-metals increase further right down a period, and further up a group. 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. 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. calling lake to athabasca
