Levels, Sublevels, Orbitals, oh my!
What sublevel is shaped like a dumbbell?
p sublevel
What is the Noble Gas notation for K?
[Ar] 4s1
How many valence electrons does He have?
two
This is the rule that states that most elements (excluding transition metals) will have a completely filled energy level at 8 electrons.
the Octet Rule
How many electrons can each orbital hold?
two
What is the Noble Gas notation for Be?
[He] 2s2
What are valence electrons?
This principle states that an electron occupies orbitals in order from lowest energy to highest.
Aufbau Principle
What neutral element is isoelectronic with N-3?
Neon
How many electrons can exist in a d sublevel?
10
What is the Noble Gas notation for Zinc?
[Ar] 4s2 3d10
How many valence electrons does C have?
four
This principle states that atomic orbitals can hold only two electrons at most and they must have opposite spins.
Pauli Exclusion Principle
What neutral element is isoelectronic with Fe+2?
Chromium
What is the highest energy level an atom can have?
7
What is the Noble Gas notation for Barium?
[Xe] 6s2
How many valence electrons does Xe have?
8
This rule states that in a sublevel with more than one orbital, put one electron into each orbital before putting 2e-into any one orbital. (electrons like to be spread out from each other, if possible)
Hund's Rule
What neutral element is isoelectronic with As-3?
[Kr]
What is an orbital?
a 3D space where an electron is MOST LIKELY to be found.
What is the Noble Gas notation for Niobium?
[Kr] 5s2 4d3
How many valence electrons does Co have?
9
What neutral element is isoelectronic with Ag+2?
Rhodium
