What does the aufbau principle suggest about electron configuration? Electrons occupy orbitals with the lowest energy first. Electrons within the same atomic orbital have different spins. Filled sublevels are more stable than partially filled sublevels. No more than two electrons can occupy the same atomic orbital.

Obitl fealds are so helpful when you are finding non orbital fealds

Explanation:

it’s; Electrons occupy orbitals with the lowest energy first.

Explanation:

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.
