orbitals and periodic Flashcards
what shape is an s orbital?
spherical
what shape is a p orbital?
dumb-bell
Pauli exclusion principles
Each orbital can hold maximum of two electrons with different spins
Hunds rule
For orbitals with the same energy, the lowest energy is when all the electrons have the same spin
the octet rule
configurations with 8 electrons in the outer most shell are very energetically stable
Who constructed the periodic table ?
Mendeleev used the similarity of chemical properties of elements to construct the periodic table
What way is the periodic table arranged by ?
Increasing atomic number
What are groups ?
elements with the same pattern of outermost (valence) electrons
What way are orbitals filled?
In order of increasing energy
How do you get the condensed electron configurations?
