Choose the correct order of electron structures from largest to smallest. a. principal energy level, sublevel, orbital, electron b. orbital, sublevel, principal energy level, electron c. electron, orbital, sublevel, principal energy level d. principal energy level, sublevel, electron, orbital

Principal energy level, sublevel, orbital, electron.  A table relating these classifications is attached.

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.

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.
