Atomic Structure Exam

Front

What is the relationship between wavelength and frequency in electromagnetic waves?

Back

Wavelength and frequency are inversely related; as wavelength increases, frequency decreases, and vice versa.

Front

What happens when an electron transitions from a higher energy level to a lower energy level in an atom?

Back

Energy is released, often in the form of light.

Front

Define quantum numbers and their significance in atomic structure.

Back

Quantum numbers describe the properties of atomic orbitals and the electrons in those orbitals, including their energy, shape, and orientation.

Front

What is the order of increasing atomic radius for elements in the periodic table?

Back

Atomic radius generally increases down a group and decreases across a period from left to right.

Front

Which orbital has the highest energy in a given electron configuration?

Back

The orbital with the highest principal quantum number (n) and the highest angular momentum quantum number (l) typically has the highest energy.

Front

What is the principal quantum number (n)?

Back

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

Front

Explain the concept of electron configuration.

Back

Electron configuration is the distribution of electrons among the various orbitals of an atom.

Front

What is the significance of the Pauli Exclusion Principle?

Back

The Pauli Exclusion Principle states that no two electrons in an atom can have the same set of four quantum numbers.

Front

Define the term 'ionization energy'.

Back

Ionization energy is the energy required to remove an electron from an atom in its gaseous state.

Front

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

Back

The ground state is the lowest energy state of an atom, while the excited state has higher energy due to an electron being promoted to a higher energy level.
