What does the Pauli exclusion principle state? No 2 electrons in a given atom can have the same direction of spin.

No 2 electrons in a given atom can occupy the same orbital. No 2 electrons in a given atom can occupy the same orbital.

No 2 electrons in a given atom can be observed at the same time.

No 2 electrons in a given orbital can have the same direction of spin.

a:

by the combination of an unlimited number of elements

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.

air

in a tire you fill a tire with air

then a couple days later you check the air pressure in the tire

hope this mark me brainliest
