Electrons in Atoms Lesson 1&2 Review

Front

Which wave type has the photons with the lowest energy?

Back

Radio waves have the lowest energy photons.

Front

What is a quantum?

Back

A quantum is the minimum amount of energy that can be gained or lost by an atom.

Front

What does the Heisenberg uncertainty principle state?

Back

It states that it is impossible to know precisely both the velocity and the position of a particle at the same time.

Front

Which statement is not true of the Quantum Mechanical model of the atom?

Back

The Quantum Mechanical model does not only apply to Hydrogen; it applies to all atoms.

Front

What is the lowest allowable energy state of an atom called?

Back

The lowest allowable energy state of an atom is called the ground state.

Front

What is the significance of the Quantum Mechanical model?

Back

It describes electrons as wave-particles and provides a framework for understanding atomic behavior.

Front

What is the relationship between energy and frequency of a photon?

Back

Energy is directly proportional to frequency; as frequency increases, energy increases.

Front

What is the photoelectric effect?

Back

The photoelectric effect is the emission of electrons from a material when it absorbs light.

Front

What is the difference between an atom's ground state and excited state?

Back

The ground state is the lowest energy state, while the excited state has higher energy due to absorbed energy.

Front

What is the principal quantum number?

Back

The principal quantum number indicates the main energy level of an electron in an atom.
