which rule describes that electrons occupying the same orbital must have opposite spin? a. Aufbaus principle b. Paulus exclusion principle c. Hinds rule d. none of the above​

b. Paul's exclusion principle

Explanation:

Let's go through the definition f each of the options and eliminate the wrong answers;

a. Aufbau's principle

This principle states that electrons fill the lower energy orbitals first before moving o higher energy orbitals. This option is wrong.

b. Paul's exclusion principle

This states that no two electrons can have the same four quantum numbers. It can also be stated that; If two electrons occupy the same orbital, they must have opposite spins. This option is correct.

c. Hund's rule

This rule states that every orbital in a sub level is singly occupied before being double occupied. This option is wrong.

d.none of the above​

a plasma is a warm ionized gasoline consisting of approximately equal numbers of definitely charged ions and negatively charged electrons. the characteristics of plasmas are notably unique from the ones of ordinary neutral gases in order that plasmas are considered a awesome "fourth kingdom of remember."
