(ii) Explain why powdered coke is sprinkled over the electrolytic mixture. So radius of potassium is higher than sodium. So its outermost orbital is unstable and they also have low ionisation enthalpy so that they easily loose their electron . Alkali metals are good reducing agents. This is because the alkali metals are good reducing agents and always lose the outer shell electron when reacting, producing an ion. By loosing that one electron they get noble gas electronic configuration. they are soft in nature All alkali metals easily remove its last shell electron to make +1 ion. Thus, they lose electrons and get oxidized themselves, hence reducing other compounds. Alkali metals are good reducing agents because alkali metals have one valence electron which they lose to attain stability. Metal hydrides, such as NaH, CaH2, and LiAlH4, which formally contain the H ion, are also good reducing agents. Therefore alkali metals can liberate H 2 by reacting with compounds which include acidic hydrogen atoms such as HCl, H 2 SO 4, alcohols, acetylene. The strength of reaction increases down the group. Note: Unexpectedly, the strongest reductant is lithium, and the weakest is sodium, because Li+ is much smaller than the other alkali metal cations. Reducing agents are those compounds or elements which can reduce others and get oxidized themselves. Good reducing agents include the active metals, such as sodium, magnesium, aluminum, and zinc, which have relatively small ionization energies and low electro-negativities. Clarification: All the alkali metals are good reducing agents due to their low ionization energies. Example : NaNH. "The Alkali Metals Are Powerful Reducing Agents arrived, looks good." Dilip Naik . Hint: Major factors that affect the magnitude of the shielding effect seen in the atoms are the number of inner-shell(s) electrons present and the type of the orbital occupied by the electrons. Alkali metals are powerful reducing agents because they only have one valence electron in their valence shell, which they may readily lose to achieve the closest noble gas configuration and become more stable than they were previously. Due to low ionization potential and having the smallest nuclear charge, they can easily lose an electron. ((2) - 1 ):1 Hence, they themselves undergo oxidation causing reduction of others and are good reducing agents. The alkaline earth metals are harder than the alkali metals, have a shine, and are good electrical conductors; less reactive than alkalis, good reducing agents, and form ionic compounds. Alkali metals are good reducing agents. Thus, act as good reducing agents. Hence, they themselves undergo oxidation causing the reduction of others and are good reducing agent. Due to this reason they undergo oxidation and other metals with them get reduced and becomes good reducing agents. the force of attraction between the nucleus and the outer electron decreases. Which metals are powerful reducing agents because? As with all metals, the alkali metals are malleable, ductile, and are good conductors of heat and electricity. They combine with other elements to form compounds. As a result, they lose one electron and oxidise while reducing others, earning the name "reducing agents."
