hunds rule

1. choose the best answer.

which rule states that no two electrons in the same atom can have the exact same set of quantum numbers?
pauli exclusion principle
hunds rule
bus seat rule
aufbau principle

Explanation:

• Question 3: Hund's rule states that orbitals of equal energy are occupied by a single electron before any orbital is occupied by a second electron. The Pauli exclusion principle states that no two electrons in an atom can have the same set of quantum numbers. The Aufbau principle is about filling orbitals from the lowest - energy to the highest - energy. "Car seat rule" is a non - scientific term.
• Question 4: The Pauli exclusion principle clearly states that no two electrons in the same atom can have the exact same set of quantum numbers. Hund's rule is about electron filling in degenerate orbitals. "Bus seat rule" is a non - scientific term. The Aufbau principle is about the order of orbital filling.

Answer:

1. Hund's rule
2. Pauli exclusion principle
