shells versus orbitals

Postby Kailie_Giebink_1E » Thu Jun 14, 2018 1:38 pm

very confused.. they seem to correlate but I can't figure out their relationships to one another.. help!

a shell contains orbitals (subshells)
for example in the second shell there is the s orbital and the p orbital
shell correlated to the period and subshells to the blocks

How do we know how many shells and orbitals there are for each atom?

The number of shells and orbitals depend on the number of electrons of the atom, thus the energy level of the atom.

Shells (represented by circles around the nucleus of an atom), represent the energy levels of an atom. The energy levels are labeled by n, with a number in front to represent which energy level the atom is one. An atom with 1-2 electrons is in the 1n shell. After this first shell, the levels increase by 8 electrons, (i.e. 3-10 electrons is in 2n, 11-18 is in 3n, etc.).

Shells can be further broken down into subshells, which are represented by letters s, p, d, and f. Each letter represents a different shape (orbital) of the atom. The level of each subshell is noted with a superscript depending on the number of electrons.
Orbitals represent a more accurate model of how electrons are distributed around an atom.

This is called ELECTRON CONFIGURATION.

Here is a link to a useful chart for electron configuration: https://goo.gl/images/s6UqRR

Hope this helps!
