Best answer. Except H2O, all hydrides of group 16 elements are reducing. Mar 20, 2020 · Group one elements are strong reducing agents because they have one valence electron in their outermost shell therefore they are loosely bound by the nucleus causing them to increase in their atomic size and as a result their ionisation potential ( minimum amount of energy to remove an electron from the outermost shell ) is less.. It uses these reactions to explore the trend in reactivity in Group 1. The Facts. General. All of these metals react vigorously or even explosively with cold water. In each case, a solution of the metal hydroxide is produced together with hydrogen gas. 2X (s) + H 2 O (l) 2XOH (aq) + H 2 (g). It becomes part of a metal solid. So there are three different things happening here: ligand dissociation, electron transfer and solid formation If we could get some physical data on each of those events, we might be able to. The reducing property depends on the ionisation potential and electron affinity of the elements. In a period, from left to right in a horizontal row of the periodic table, the atomic size decreases and the nuclear charge increases, so the electron affinity and ionisation energy both increase.. So, as the bond strength decrease, the ease to produce increase along with the group. Hence, the reducing character of group 15 hydrides increases down the group. Therefore, the trend of the reducing strength is: BiH 3 > SbH 3 > AsH 3 > PH 3 > NH 3 Hence, the reducing character of hydrides of group 15 elements increases from top to bottom.

1 Answer. Sorted by: 1. Alkali metal hydrides can typically be viewed as labile hydride anions. The extent of lability can correlate with the electronegativity of the metal. Hence, less electronegative metals in alkali metal hydrides yield more labile hydride anions and more "reducing" nature. Share. Improve this answer. . 10. The correct order of reducing property of dioxides are. TeO 2 >SeO 2 >SO 2. SO 2 >SeO 2 >TeO 2. SeO 2 >TeO 2 >SO 2. None of these. See Answer. × Group 15 Elements Dinitrogen and Ammonia Oxides of Nitrogen and Nitric acid Phosphorus-Allotropic forms and phosphine Phosphorus Halides and Oxo-acids of Phosphorus Group 16 Elements MCQ. .

The reducing power of elements increases as one goes down a group?. Common reducing agents include metals potassium, calcium, barium, sodium and magnesium, and also compounds that contain the hydride H − ion, those being NaH, LiH, LiAlH 4 and CaH 2.. Some elements and compounds can be both reducing or oxidizing agents. Hydrogen gas is a reducing agent when it reacts with non-metals and an oxidizing agent when it reacts with metals.

Feb 19, 2018 · Reducing power depends upon the ease of ejection of electron from an atom. As we move down the group, effective nuclear charge decrease, therefore electron can be easily ejected and reducing power increases. In period effective nuclear charge increases, therefore ejection of electron becomes difficult and reducing power decreases..

The reducing power INCREASES down the group 13 From top to bottom reduction potentials values become positive i.e. top to bottom in the elements of the group 13 reducing character decreases. The order of decreasing of reducing power is Al > Ga >In> Tl. The above statement is TRUE. sorry I misunderstood the question no problem :) Advertisement. Trends in Group 2 Compounds. Group 2 Elements are called Alkali Earth Metals. They are called s-block elements because their highest energy electrons appear in the s subshell. Progressing down group 2, the atomic radius increases due to the extra shell of electrons for each element. Going down the group, the first ionisation energy decreases. a Group 1 elements are strong reducing agents State and explain the trend of. A group 1 elements are strong reducing agents state.
