Discovered electron
JJ Thomson?
electrons are added one at a time to the lowest energy orbitals avaliable
What is aufbau principle
groups 3-12 of the periodic table
What is transition metals
an atom that has a positive or negitive charge
What is an ion
oxygen for this number of covalent bonds
two (double bond)
Shape of orbital ... quantum number
angular momentum
In pure form ... they are diatomic molecules
What is halogens
composed of positive and negitive ions that are combined so that the numbers of positive and negitive are equal
What is an ionic compound
carbon forms this many covalent bonds
What is four
An orbital can only hold 2 electrons
What is Pauli exclusion principal
negative ion
What is an anion
intermolecular force between hydrogen and more electronegitive atoms
What is hydrogen bonding
First quantum model
Bohr
Electrons occupy equal-energy orbitals so that a max # of unpaired electrons result.
What is Hund's rule
Never found pure in nature because too reactive
What is Alkali metals
Holds Fe, Cu, Al, etc together
metallic bond
Wrote wave function equation
Schrodinger
Size of the Orbital
What is Principal
gases at room temp. Brittle, poor conductors
What is non-metals
positive ion
What is a cation
weakest intermolecular force
London dispersion force
