NettetGroup 18 of the periodic table exhibits lowest reactivity. Elements with a full outermost valence shell, i.e., those with eight electrons in the outer shell, such as helium, neon, radon and others are the least reactive. Noble gases cannot gain or lose valence electrons by interacting with other elements, making them most stable or least reactive. Nettet3. jan. 2024 · The non-metal elements in Group 7 – known as the halogens – get less reactive as you go down the group. This is the opposite trend to that seen in the alkali metals in Group 1 of the periodic ...

NettetTherefore, leaving groups that form resonance structures upon leaving are considered to be excellent leaving groups. The following diagram shows sulfur derivatives of the type ROSO 3- and RSO 3-. Alkyl sulfates and sulfonates like the ones shown make excellent leaving groups. This is due to the formation of a resonance stabilized structure upon ... Nettet7. des. 2009 · The least reactive elements in the Periodic Table are the noble gases or sometimes the inert gases.
