How many possibilities or shapes does each atomic orbital have?
s - 1 p - 3 d - 5 f - 7
How do you find the maximum amount of electrons an orbital can hold?
Knowing that each can hold up two 2 electrons, simply multiply by the maximum number of shapes.
What does the azimuthal quantum number determine?
what kind of orbital the atom is in s - 0 p - 1 d - 2 f - 3
Hund’s Rule
Electrons will not pair up to occupy the same orbital
Aufbau Principle
electrons will fill the lowest energy orbital first
In general, valence electrons are the outer values of an atom’s electron configuration, while the core are on the inside. What is one exception to this rule?
d shell electrons are considered valence electrons
What atoms are the exceptions to the electron configuration rules?
chromium, copper, molybdenum, gold, and silver
Paramagnetic includes _____ electrons which are ______ to magnets. Diamagnetic includes _______ electrons which are ____ to magnets.
paramagnetic - unpaired, attracted diamagnetic - paired, repel
T/F - The photoelectric effect is observed when a metal is hit with photons to release energy.
False - when a metal is hit with energy, it will emit an electron.
Heisenberg Uncertainty Principle
It is impossible to determine a subatomic particle’s location and its momentum with perfect accuracy
When ionic compounds form, the metal will give its electron to the nonmetal and become _____, while the nonmetal will become ____.
cation, anion
Lattice energy
the energy needed to separate an ionic compound’s cations and anions
In order to have a large lattice energy, there needs to be a ___ bond distance and ____ charge
short, large
What is the formula for formal charge?
FC = (valence electrons) - (number of dots) - (number of lines)
T/F? Because pi bonds are found in both double and triple bonds, these are stronger than sigma bonds, which are found in single bonds.
FALSE - sigma bonds are actually stronger than pi!
In regards to bond order, an AVERAGE length that is longer is typically: a) stronger b) weaker c) cannot be determined without data
A
List the hybridization for the following number of “things” around a central atom - 2, 3, 4, 5, 6
2 - sp 3 - sp2 4 - sp3 5 - sp3d 6 - sp3d2
