WebMar 29, 2024 · In fact, they are the most reactive metals and, along with the elements in group 17, are the most reactive of all elements. The reactivity of alkali metals increases from the top to the bottom of the group, so lithium (Li) is the least reactive alkali metal and francium (Fr) is the most reactive.Platinum is the least reactive metal. WebAug 13, 2024 · The most reactive element in group 1 is casesium because as we come from top to bottom, the size of atom is increased in the parallel with the number of electron, so the strength to held the electron decrease, and we know that all alkali metal have one electron in outer most shell so it can be very easy to remove that electron from casesium.

WebJul 14, 2024 · Platinum is the least reactive metal. It has remarkable resistance to corrosion, even at high temperatures, and is therefore considered a noble metal. ... The best conductor of electricity is pure silver, but to no surprise, it is not one of the most commonly used metals to conduct electricity. WebAssertion : Platinum, gold and silver are used to make jewellery. Reason : Platinum, gold and silver are least reactive metals. (a) Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A). Platinum, gold and silver are highly malleable lustraus and least reactive, i.e. noble metals, so they are not iowa aftercare

WebSuch elements are also identified as reducing agents, as they reduce the other species/element present in the reaction mixture. As is evident from the above reactivity series, among iron (Fe), copper (Cu), aluminium (Al), and calcium (Ca), Copper is placed at the lowest position i.e., it is the least reactive metal. Download Solution PDF. WebMay 5, 2024 · Yes, alkali metals are more reactive than alkaline-earth metals. All atoms want to have 8 electrons in their outer shells. Alkali metals have to give one electron away, where as alkaline-earth metals need to give two away which is less energetically favorable. GCSE Chemistry - Group 1 Alkali Metals #11.
