Current Model of the Atom. current model based on quantum theory electrons exist in probability clouds called orbitals electrons do NOT orbit nucleus in circular pattern How can we keep track of the electrons?. Notation.
All s subshells contain a single orbital called an s orbital. Every s orbital is spherical; the difference between a 1s, 2s, 3s, etc. is the size.
All p subshells contain three orbitals called
p orbitals, one on each of the three axes.
Every p orbital is dumbbell shaped; the
difference between 2p, 3p, 4p, etc. is the size.
All d subshells contain five orbitals called
The difference between 3d, 4d, etc. is the size.
An electron configuration shows the distribution of electrons among the subshells of an atom. Fill in order shown (max 2 electrons for s, 6 for p, 10 for d, 14 for f)
6s 6p 6d 6f
5s 5p 5d 5f
4s 4p 4d 4f
3s 3p 3d
The electrons in the outer most shell are
called the valence electrons. Electrons in the
inner shells are core electrons.
Give the electron configuration, and determine
the number of valence electrons for. . .
