What is the general valence-electron ground-state electron configuration for neutral alkaline earth metals?

nS²

According to the periodic law, elements that fall into the same group have similar properties.

All the alkaline earth metals are in group two of the periodic table. The have 2 electrons in their outermost shell. In the SPDF electronic configuration the ground state of all alkaline earth have S² two electrons in their outermost S sublevel.

Example the electronic configuration of some alkaline earth metals are

Beryllium [He] 2S²

Magnesium is [Ne] 3S² and

Calcium is [Ar] 4S²

the general electronic configuration for alkaline earth metals is nS²

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
