is an integer from-l through 0 to +l, called the magnetic quantum number, prescribing the 3D orientation of the orbital of in the space around the nucleus.
a measure of the probability of finding an electron of a particular energy in a particular region of the atom.
An atomic orbital is specified by
three quantum numbers. they are: principle quantum number (n), angular momentum (l), magnetic quantum number (m_l).
a positive integer
Indicates the relative size of the orbital and relative distance from the nucleus
the smaller the n value the lower the ...
energy level and the greater the probability the electron is closer to the nucleus
described by each combination of n, l, and ml, specifies the size (energy), shape, and spatial orientation of one of the atom's orbitals
Pauli's exclusion principle
No two electrons in the same atom can have the same four quantum numbers
The energies of atomic orbitals are affected by
nuclear charge (Z), and shielding by other electrons
Energy states of many-electron systems are affected by ________ which gives rise to ______.
electron-electron repulsions/the splitting of energy levels into sublevels
The further from the nucleus an electron is, the lower the
Zeff for that particular electron. (effective nuclear charge)
Orbital shape causes electrons in some orbitals to ____________ close to the nucleus.
Orbital shape causes electrons in some orbitals to "penetrate" close to the nucleus.
specifies that when orbitals of equal energy are available, the lowest energy electron configuration has the maximum number of unpaired electrons with parallel spins
Inner (core) electrons are those an atom has in common with
the pervious noble gas and any completed transition series
