Orbitals
Oxygen has this number of electrons.
What is 8?
Aufbau's Principle states...
What is the order of filling; the lowest energy orbitals are filled first?
Hund's Rule states...
What is equal energy orbitals (in the same sublevel); each orbital must be half filled before one is filled?
Pauli's Exclusion Principle states...
two electrons in the same orbital in the same sublevel can not have the same spin state.
no 2 electrons can have the same 4 quantum numbers
the sublevel that has a shape that consists of two dumbbells.
What is d?
The mistake in.. ↑↓ ↑↓ ↑↓ ↑↓ ↑↓ ↑ ↑ ↑ ↑ 1s 2s 2p 3s 3p
What is.. 3s was not filled before 3p was; the lowest orbitals must be filled before the others are?
The mistake in... ↑↓ ↑↓ ↑↓ ↑↓ ↑↓ ↑↓ ↑↓ ↑ _ 1s 2s 2p 3s 3p
3pz orbital must be half filled before 3px can be filled
The mistake in.. ↑↓ ↑↓ ↑↓ ↑↓ ↑↓ ↑↑ 1s 2s 2p 3s
in orbital 3s the electrons have the same direction of spin. This breaks Pauli's exclusion Principle because no 2 electrons can have the same 4 quantum numbers.
The number of electrons that can fit into an f orbital
What is 14 electrons?
The electron configuration of.. 1s^2, 2s^2, 2px^1, 2py^1, 2pz^1
What is.. 1s^2, 2s^2, 2p^3
This can break Aufbau's Principle.
What is excited state?
The number of electrons in the 3s orbital for Phosphorus, follwing Hund's Rule.
is 2
show an orbital diagram that would violate the Pauli exclusion principle for Mg (Atomic Number 12).
2 arrows in the same orbital that are both up or both down.
The number of half filled orbitals in Nitrogen.
What is 3?
The element that has the electron configuration.. 1s^2, 2s^2, 2p^6, 3s^2, 3p^6, 4s^2, 3d^4
What is Chromium (Cr)?
Excited state is..
What is when the electrons jump from lower to higher energy levels, therefore breaking Aufbau's Principle.
The mistake if two electrons lie in 2px and 1 in 2py.
2pz needs an electron before 2px can be filled
The 4 quantum numbers are...
principle quantum number , angular momentum , magnetic and spin quantum number.
The number of half filled orbitals in the element Palladium having atomic number 46.
What is 2?
The electron configuration for the element Molybdenum (Mo) - 42
What is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 4d6 ?
The opposite of excited state is.
What is ground state?
Give the noble gas notation for Potassium.
[Ar] 4s(1)
how many electrons does an element have with and electron configuration of [Ar] 3d(4),4s(2).
