2.2 Electron configuration Flashcards
what is the formula relating velocity, wavelength and frequency?
c = v λ
c: velocity
v: frequency
λ: wavelength
what are the 7 different types of electromagnetic radiation, ranked from lowest to highest frequency?

- X - ray
- Gamma ray
what are the 7 different colours of visible light?
the rainbow
- red
- orange
- yellow
- green
- blue
- indigo
- violet
why does convergence occur?
it occurs because an atom’s outer energy level are closer together the higher they are
how many electrons does each energy level hold?
2n^2
what are the 4 orbitals?
s, p, d and f
which groups have s orbital?
group 1, group 2 and helium
which groups have p orbitals?
group 13 -18 without helium
which groups have d - orbital?
group 3 - 12
which groups have f - orbitals?
lanthanides and actinides
explain the aufbau principle
lowest energy orbitals are filled first!!
explain hund’s rule
all sub-orbital are filled with one electrons first
explain the pauli exclusion principle
orbitals contain a maximum of 2 electrons that have opposite spins
which 2 d-block elements do not contain a full 4s sub shell?
copper and chromium
what is the condensed electron configuration of copper?
[Ar] 4s^1 3d^10
what is the condensed electronic configuration of chromium?
[Ar] 4s^1 3d^5
