The elements which have 2 electrons in their outermost cell are generally?
Anon-metals
Bmetalloids
Cnoble gases
Dmetals
Answer:
D. metals
Read Explanation:
Elements with two electrons in their outermost shell are generally alkaline earth metals.
Elements possessing two electrons in their outermost electron shell typically belong to the alkaline earth metals (Group 2) of the periodic table.
These two valence electrons are readily lost, resulting in the formation of stable divalent cations (+2 charge).
This characteristic electron configuration is responsible for their similar chemical properties, such as being reactive metals that form basic oxides and hydroxides, although generally less reactive than the alkali metals of Group 1.
