review notes, labs, worksheets (memorize blue sheet)

what does c stand for?

speed of light; 3 × 10^8 m/s

what does v stand for?

frequency (in Hz)

what does λ stand for?

wavelength (in m or nm)

what does h stand for?

Planck's constant; 6.626 × 10^-34

what does c =

λ x v

what does E =

h x v or (h x c) / λ

orbitals

geometric shapes around nucleus where electrons are found

what does each row on the periodic table represent?

energy level

how many energy levels are there?

7

what are the 4 types of atomic orbitals?

s, p, d, f

how many electrons can the s orbital hold

2

how many electrons can the p orbital hold

6

how many electrons can the d orbital hold

10

how many electrons can the f orbital hold

14

how many valence electrons can there be?

8 when full

what does each block on the periodic table represent

types of atomic orbitals

what shape does the s orbital have

circle

what shape does the p orbital have

figure 8 / infinity

what are the 3 rules of electron configuration

aufbau principle, pauli exclusion principle, hund’s rule

aufbau principle

electrons enter the lowest energy orbitals first

pauli exclusion principle

atomic suborbital may have up to 2 electrons and they must be paired in opposite directions

hund's rule

when you have degenerate (same energy) orbitals, fill each suborbital up halfway, then pair electrons together

electron configuration (notation)

n + orbital + # electrons in orbital; for example 1s¹ is hydrogen

what does n represent?

energy level

how are energy levels arranged?

lower the energy level, closer it is to the nucleus

orbital notation

make boxes for each suborbital, follow 3 rules of electron configuration and use arrows to indicate direction of electrons

noble gas notation

shortened way of expressing electron configuration; use noble gas (last row on the periodic table) right before the element and put it in brackets, then continue electron configuration

electron configuration exception

silver and chromium’s row have the s and d orbitals swapped

electron configuration of sodium (Na)

1s² 2s² 2p⁶ 3s¹

electron configuration of Barium (Ba)

1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶ 5s² 4d¹⁰ 5p⁶ 6s²

orbital notation of phosphorous (P)

what is the noble gas notation of magnesium (Mg)?

[Ne] 3s²

what is the correct electron configuration of silver (Ag)

[Kr] 4d¹⁰ 5s¹
