QUANTUM NUMBERS

Question 1

nucleus surrounded by
electrons

Answer 1

bohr’s atomic model

Question 2

electrons moving in fixed
orbitals (shells), each shell
with fixed energy

Answer 2

bohr’s atomic model

Question 3

electrons can move into
different orbits

Answer 3

bohr’s atomic model

Question 4

• assumes electron as a wave
• predicts the position of the electrons and the probability for the electron to be in that position

Answer 4

schrödinger’s model

Question 5

states that it is impossible to measure or calculate exactly both the position and the momentum of an object

Answer 5

Heisenberg uncertainty principle

Question 6

the smallest quantity of
a property

Answer 6

quantum – (plural: quanta)

Question 7

measured in discrete values

Answer 7

quantized

Question 8

the circular paths around the nucleus of an atom which the electrons move

Answer 8

shell

Question 9

a path taken by electrons as they move around within the shell’s confines
- one or more of these are in a shell
– s, p, d, f

Answer 9

subshell

Question 10

the space where the probability of finding
an electron is the highest

Answer 10

orbital

Question 11

science dealing with the behavior of matter and
light on the atomic and subatomic scale

Answer 11

QUANTUM MECHANICS

Question 12

explains how extremely small objects simultaneously have the characteristics of particles and waves

Answer 12

QUANTUM MECHANICS

Question 13

describe the distribution and behavior of electrons within an atom.

Answer 13

Quantum numbers

Question 14

describe the location
of the electrons (3)

Answer 14

• principal quantum number
• angular momentum quantum number
• magnetic quantum number

Question 15

describes the behavior of
a specific electron

Answer 15

spin quantum number

Question 16

states that no two electrons can share the same combination of the four quantum numbers.

Answer 16

Pauli Exclusion Principle

Question 17

• describes the probable distance of the electrons
  from the nucleus (thus, the orbital size and
  energy level)
• any positive integer that starts at 1

Answer 17

PRINCIPAL QUANTUM NUMBER (n)

Question 18

• tells the “shape” of the orbitals
• depends on the value of the principal quantum
  number

Answer 18

ANGULAR MOMENTUM QUANTUM NUMBER (l)

Question 19

• describes the orientation of the orbital in space
• depends on the value of l

Answer 19

MAGNETIC QUANTUM NUMBER

Question 20

describes the direction of the spinning motion of
an electron (assumed to act like a tiny magnet)

Answer 20

ELECTRON SPIN QUANTUM NUMBER
