Light + energy

energy levels filled in order of increasing energy

equal energy orbitals filled with one electron each before pairing can occur

electrons in an orbital must have opposite spins

What is the first quantum number?

The first quantum number is n.  Therefore, n specifies the atoms major energy levels, called _______________.

The second quantum number is

spherical

• states that it is fundamentally impossible to know precisely both the velocity and the position of a particle at the same time.

which quantum is: energy sublevels, orbital shapes (s, p, d, f)

which quantum is the plain of existence (x, y, z)
