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. WebLeast reactive? 2.What is the trend of reactivity of metals across (--›) a period? 3.What is the trend of reactivity of metals down a group? a group? 4. the order of reactivity of metals from the most reactive down to the least reactive is called? 5. What will be formed when a reactive non-metal and reactive metal combined? . 6.
What Is The Most Reactive Metal - BRAINGITH
WebJul 15, 2024 · Why reactivity of metals increase down 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. 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 … foldable outdoor furniture sets

WebLeast reactive group. Alkali Metals (Group 1 elements) + H2O Example Li + H 2 O -> LiOH + H 2 Atomic size Atomic size increases going down a column (group) • This is because each row you go down, the number of shells goes up by 1. e.g row 2 elements have 2 shells whereas row 7 elements have 7 shells. 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 … WebAug 21, 2024 · Group 2 elements (beryllium, magnesium, calcium, strontium and barium) react oxygen. to generate metal oxides. This Module addressed why it is difficult to observe a tidy pattern of this reactivity. Formation of simple oxides On the whole, the metals burn in oxygen to form a simple metal oxide. eggless pancakes without baking powder
