5.2-5.3

Question 1

quantum state

Answer 1

A specific combination of values or variables such as energy and position that is allowed by quantum theory; it means that only certain amounts of energy & wavelengths are allowed

Question 2

frequency

Answer 2

The rate at which an oscillation repeats- 1 Hz is equal to 1 oscillation per second.

Question 3

energy level

Answer 3

In an atom, the set of quantum states that have approximately the same energy; indicated on the periodic table by the horizontal row an element is found in.

Question 4

Plank’s constant

Answer 4

A number which defines the scale of energy at which quantum effects must be considered; h = 6.625 x 10⁻³⁴J x s

Question 5

quantum theory

Answer 5

A set of explanations in chemistry and physics that accurately describes the universe on very small scales such as the inside of an atom.

Question 6

quantized

Answer 6

Refers to the fact that electrons can possess only certain discrete energy values and when excess energy is absent, atoms (electrons) drop below this level by emitting a photon of light at a particular wavelength.

Question 7

Pauli Exclusion Principle

Answer 7

States that 2 electrons in the same atom may never be in the same quantum state.

Question 8

photon

Answer 8

The smallest possible quantity (or quanta) of light; light exists in discrete bundles of energy.

Question 9

wavelength

Answer 9

The distance (separation) between any two successive peaks (or valleys) of a wave.

Question 10

orbital

Answer 10

A group of quantum states that have similar spatial shapes, labeled s, p, d, and f.

Question 11

calcium emission spectrum

Answer 11

Shows that calcium atoms (electrons) if they are excited enough, may release up to 16 photons of light at different wavelengths when losing energy and returning to ground state.

Question 12

Hund’s rule

Answer 12

Every orbital in a subshell is singly occupied with one electron before any one orbital is doubly occupied, and all electrons in singly occupied orbitals have the same spin.

Question 13

electron configuration

Answer 13

A description of which orbitals contain electrons for a particular atom

Question 14

principal quantum number

Answer 14

A number that specifies the quantum state and is related to the energy level of the electron

Question 15

spectrum

Answer 15

A representation that analyzes a sample of light into its component energies of colors, can be a picture, graph or a table of data
