Atoms and Electrons
He proposed a model where electrons orbit the nucleus in specific energy levels.
Who is Niels Bohr?
This term describes a region of space where electrons are likely to be found.
What is an orbital?
This particle of light carries energy.
What is a photon?
When an electron releases energy, it undergoes this process.
What is emission?
This quantum number indicates the size and energy level of an orbital.
What is the principal quantum number?
This diagram involves dotting.
What is Lewis Dot?
This rule states that electrons fill the lowest available energy levels first.
What is the Aufbau principle?
This term measures the distance between two peaks of a wave.
What is wavelength?
When an electron absorbs energy and moves to a higher energy level, it undergoes this process.
What is absorption?
Each electron has these many sets of quantum numbers.
What is four?
Electron in the highest energy level
What is a Valence electron?
This rule states that electrons will fill each orbital in a sublevel singly before pairing.
What is Hund's rule?
This measures how many waves pass a point per second.
What is frequency?
This term describes an atom with electrons in the lowest possible energy levels.
What is the ground state?
This quantum number determines the orientation of the orbital.
What is the third?
Electrons reside here in a quantum model.
What are clouds or orbitals?
This notation represents electrons using numbers, letters, and superscripts.
What is electron configuration notation?
This term refers to the full range of electromagnetic waves.
What is the electromagnetic spectrum?
This term describes an atom with electrons in higher energy levels after absorbing energy.
What is an excited state?
The d sublevel can hold this maximum number of electrons.
What is ten?
The Noble Gas Configuration for Chromium.
[Ar] 3d⁵ 4s¹.
This term refers to the specific level of energy an electron can occupy.
What is an energy level?
This constant relates energy to frequency in quantum mechanics.
What is Planck's constant?
This energy is required to remove an electron from an atom.
What is ionization energy?
The p sublevel has this number of orbitals.
What is three?
