What is an Energy-level (orbital) Diagram?
A diagram that represents the relative energies of the electrons in an atom
What does the Electron Configuration describe?
The location and number of electrons in the electron energy level of an atom
What is the Aufbau Principle?
Electrons are filled in the lowest energy available orbitals first
Fill in the blank: According to Hund’s Rule, before any two electrons can occupy an orbital in a sublevel, the other orbitals in the same sublevel must contain _______.
one electron
What does the Pauli Exclusion Principle state?
No two electrons can have the same set of 4 quantum numbers
What should you do for anions when drawing Energy-level Diagrams?
Add extra electrons to the neutral atom
What is the first step for drawing Energy-level Diagrams for cations?
Start with the neutral atom
When subtracting electrons for cations, which electrons should be removed first?
Electrons starting from the highest principal quantum number (n)
What is the electron configuration for Boron?
1s² 2s² 2p¹
What is the electron configuration for Nitrogen?
1s² 2s² 2p³
What does Ms stand for in magnetic properties?
Ms refers to saturation magnetization.
What creates little magnetic fields as electrons spin?
The spin quantum number.
What type of atoms are attracted to a magnet due to unpaired electrons?
Paramagnetic atoms.
What happens to the polarity of a magnetic field when electrons have opposite spins?
They will cancel each other out.
What is the term for atoms with no unpaired electrons?
Diamagnetic.
Fill in the blank: Atoms with unpaired _______ will be attracted to a magnet.
electrons.
True or False: Diamagnetic materials have a net magnetic field.
False.
What is the result of an atom having no unpaired electrons?
It will have no net magnetic field.
