Question 1

Principal quantum number (n) / shell

Answer 1

Related to average distance of the electron from the nucleus

Question 2

Sublevel / subshell (l)

Answer 2

Values range from 0 to n-1
Value designates the sub level and represents shape of the orbitals

Question 3

Sub level numbers (1) and letters

Answer 3

0, s
1, p
2, d
3, f

Question 4

Orbital

Answer 4

Region of space with high electron density (s p d f according to the sublevel)

Question 5

Formula for number of orbitals in a sublevel (azimuthal quantum number)

Answer 5

2l + 1

Question 6

Magnetic quantum number (ml)

Answer 6

An integer from -l to l that designates the orientation of the orbital in space

Question 7

Spin quantum number (ms)

Answer 7

+-1/2

Question 8

Pauli Exclusion Principle

Answer 8

No two electrons in the same atom can have the same four quantum numbers

Question 9

Hund’s Rule

Answer 9

p, d, or f orbitals in a sublevel must all be filled with an electron before a second electron can pair in any orbital

Question 10

Allotrope

Answer 10

An element with two or more distinct sets of chemical and physical properties
Example - O2 and O3 are allotropes of oxygen

Question 11

Trend in melting and boiling points of metals

Answer 11

Decrease from top to bottom of a group

Question 12

Trend in melting and boiling points of nonmetals

Answer 12

Increase from top to bottom of a group
