Hydrogen Atom and Electron Configurations Remediation Assignment

Front

What is the Aufbau principle?

Back

The Aufbau principle states that electrons occupy the lowest energy orbitals first before filling higher energy levels.

Front

What does the Pauli exclusion principle state?

Back

The Pauli exclusion principle states that no two electrons in the same atom can have the same four quantum numbers.

Front

What is Hund's rule?

Back

Hund's rule states that electrons will fill degenerate orbitals (orbitals of the same energy) singly before pairing up.

Front

What is the significance of the quantum number 'n'?

Back

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

Front

What is an absorption line?

Back

An absorption line is a dark line in a spectrum that occurs when an atom absorbs specific wavelengths of light, indicating energy absorption.

Front

How do electrons transition between energy levels?

Back

Electrons can transition between energy levels by absorbing or emitting energy, often in the form of photons.

Front

What is the electron configuration for Fluorine (atomic number 9)?

Back

The electron configuration for Fluorine is 1s² 2s² 2p⁵.

Front

What is the relationship between wavelength and energy?

Back

The energy of a photon is inversely proportional to its wavelength; shorter wavelengths correspond to higher energy.

Front

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

Back

When an electron transitions from a higher to a lower energy level, it emits energy, often in the form of light.

Front

What is the Bohr model of the atom?

Back

The Bohr model describes the atom as having electrons in fixed orbits around the nucleus, with quantized energy levels.
