• sp

How do electrons exist in atomic orbitals?

• As particles

• As standing waves

• As moving clouds

• As fixed points

What is the role of higher-order orbitals like d and f?

• They contribute to complex geometries

• They are not involved in bonding

• They only exist in gases

• They are irrelevant to chemistry

How does molecular shape affect chemical behavior?

• It dictates properties like polarity and reactivity

• It only affects color

• It has no effect

• It only affects taste

What is the relationship between electron clouds and atomic stability?

• Electron clouds increase energy and destabilize atoms

• Electron clouds have no effect on stability

• Electron clouds destabilize atoms

• Electron clouds help minimize energy and stabilize atoms

Why is understanding quantum chemistry important?

• It is not important

• It is only important for physicists

• It is essential for fields like materials science and pharmacology

• It is only relevant to astronomers
