Muaj pes tsawg valence electrons pom nyob rau hauv halogens cov alkali hlau thiab alkaline ntiaj teb hlau?

Cov halogens tag nrho muaj cov txheej txheem hluav taws xob dav dav ns2np5, muab rau lawv xya valence electrons. Lawv yog ib qho hluav taws xob luv luv uas muaj tag nrho sab nrauv s thiab p sublevels, uas ua rau lawv muaj zog heev. Lawv tau txais cov tshuaj tiv thaiv tshwj xeeb nrog cov reactive alkali hlau

Puas yog cov hlau tsis ua rau cov kua qaub?

Feem ntau, cov non-metals tsis hnov mob nrog dilute acids. Qhov no yog vim hais tias thaum ib yam khoom reacts nrog acids, nws muab electrons rau H + ions uas ua los ntawm cov kua qaub. Cov hlau tsis muaj hlau yuav nquag tsis hnov mob nrog dej, txawm li cas los xij, cov hlau tsis yog hlau oxides yuav hnov mob nrog dej los tsim cov kua qaub

Yuav ua li cas yog qhov tshwm sim uas ib tug poj niam dig muag xim uas yuav ib tug txiv neej uas tsis pom kev zoo yuav muaj xim dig muag me nyuam?
