Valence Electrons and the Periodic Table
 
16:53
To see all my Chemistry videos, check out http://socratic.org/chemistry Where do electrons live in atoms? They live in energy levels or shells, which are varying distances from the nucleus, and can hold varying numbers of electrons. The most important electrons in an atom are the valence electrons, which are in the outermost energy level or shell. We'll look at how to determine the number of valence electrons in an atom, based on which column it is in on the periodic table.

How to Find Valence Electrons! (and Total Electrons)
 
09:28
You can find valence electrons with a shortcut using the periodic table, but it’s good to only do that after you understand why the shortcut works, and to do that you have to draw out the full electrons and orbitals for a few different atoms. Valence electrons are just electrons in the last orbital, they are different from core electrons, which are the total number of electrons except the valence.

Transition metals are the elements in the middle of the periodic table, and compounds with transition metals have roman numerals in them. Transition metal elements are able to make multiple ions with different charges, so we need to use roman numeral notation (sometimes called Stock notation) to show what charge the ions have.

005 - Electron Configuration In this video Paul Andersen explains how to write out the electron configuration for atoms on the periodic table. More importantly he shows you why electrons arrange themselves in shells, subshells and orbitals by using Coulomb's law and studying the first ionization energies of different atoms. ANSWERS: Cl - [Ne] 3s^2 3p^5 Ag - [Kr] 4d^10 5s^1 - Did you get [Kr] 5s^2 4d^9? There are a few exceptions to this law. Most of them are found in the f-block metals and they are not of much chemical significance.
