What is the Aufbau Principle?
What is the Pauli Exclusion Principle?
A single orbital can only hold one electron
That a single orbital can hold a maximum of two electrons with opposite spins.
That a single orbital can hold a maxiumum of 9 electrons
Orbitals dont fit any electrons
What is Hund's Rule?
When filling a subshell with electrons, each orbital within that subshell must be occupied singly (with the same spin) before pairing begins.
Which one of these follows Hund's rule?
Which one correctly demonstrates Pauli Exclusion principle?
Draw the orbital diagram with the up-spin and down-spin electrons for an oxygen atom.
Select the noble gas configuration for the element Polonium.
(Noble gas notation uses the noble gases as a shortcut)
(For example: [Kr] is shortcut for 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6)
[Xe] 6s² 4f¹⁴ 5d¹⁰ 6p⁴
[He] 6s² 4f¹⁴ 5d¹⁰ 6p²
