Orbital Diagrams

What does Hund's rule state about electron behavior in orbitals?

• Electrons fill up orbitals to maximize their proximity to each other.

• Electrons remain unpaired and occupy the same orbital.

• Electrons fill orbitals such that they are as unpaired as possible when multiple orbitals are available.

• Electrons prefer to pair up immediately.

What is the electron configuration notation for a fully filled s orbital in nitrogen?

• 1s2

• 1s1

• 2s2

• 2p2

How are electrons distributed in the p orbitals according to Hund's rule?

• All electrons are paired in one orbital before filling the next.

• Electrons fill each orbital singly before any orbital is doubly filled.

• Electrons randomly fill available p orbitals.

• All p orbitals remain empty until s orbitals are filled.

What does it mean if an element is described as 'paramagnetic'?

• It has no electrons.

• All of its electrons are paired.

• It has unpaired electrons and is attracted to magnets.

• It repels magnetic fields.

Which term describes substances with all electrons paired?

• Paramagnetic

• Diamagnetic

• Hydrophobic

• Hydrophilic
