Atomic Orbitals and Energy States Quiz

How can we model the energy states of electrons in atoms?

• By using atomic orbitals

• By measuring atomic mass

• By observing chemical reactions

• By calculating atomic number

In the Bohr model of the atom, how do electrons travel around the nucleus?

• In random paths

• In specific orbits

• In a straight line

• In a zigzag pattern

What does each orbit in the Bohr model have?

• The same energy

• A different energy

• No energy

• Infinite energy

What is the ground state of an atom?

• When electrons occupy the highest energy orbital

• When electrons are in a higher energy level

• When all electrons occupy the lowest energy orbital

• When electrons are shared between atoms

What is the excited state of an atom?

• When all electrons are in the lowest energy level

• When one or more electrons are in a higher energy level

• When electrons are in the same energy level

• When electrons are removed from the atom

What happens when electrons move from a higher energy orbit to a lower one?

• The atom becomes larger

• The atom emits light

• The atom loses mass

• The atom gains energy

What is true about a lower energy photon?

• It has a shorter wavelength

• It has a longer wavelength

• It has a higher frequency

• It has more energy

What principle can be applied to deduce electron configurations for atoms and ions up to Z = 36?

• Bohr's model

• Aufbau principle

• Rutherford model

• Quantum theory

What is the electron configuration of the potassium ion (K⁺)?
