A region of high probability of finding an electron
What is an atomic orbital?
States that electrons tend to fill the lowest energy orbitals first.
What is the Aufbau principle?
A discrete bundle, or quantum, of electromagnetic energy.
What is a photon?
The principal quantum number identifies this property of an electron.
What is the energy level?
This is involves the probability of finding an electron in a certain position.
What is the quantum mechanical model?
The lowest energy arrangement of an atom.
What is the ground state?
States that an orbital can hold at most two electrons.
What is the Pauli exclusion principle?
The number of wave cycles passing a point per unit of time.
What is frequency?
This is the shape of an s orbital.
What is spherical?
Bohr's atomic model was valid only for this element.
What is hydrogen?
The arrangement of electrons around an atomic nucleus.
What is an electron configuration?
This states that it is impossible to know both the position and velocity of a particle at the same time.
What is the Heisenberg uncertainty principle?
The distance between wave crests.
How many sublevels are in the third principal energy level?
What is 3?
Occurs when an electron jumps from a higher energy state to a lower energy state.
What is gives off light?
The frequencies of light emitted by an element.
What is an atomic emission spectrum?
How should 4 electrons be added to a p sublevel? Illustrate using an orbital diagram.
One at a time with the same spin until they begin to pair. The first should have two arrows, one up and one down. The last two orbitals should have one arrow each, pointing in the same direction.
Wavelength and frequency are _____________ proportional.
What is inversely?
What is 7?
The two types of sublevel electron configurations that are most stable.
What are filled and half-filled?
The energy needed to move an electron from one energy level to another.
What is a quantum?
Which orbital should be filled first? 3d or 4s?
Which color of visible light has the shortest wavelength?
violet
This is the number of electrons in the third energy level.
What is 18?
The formula is 2n^2.
The equation that relates energy to frequency.
