Name An Element In The Fourth Period Of The Periodic Table With 5 Valence Electrons., 3.71 MB, Finding the Number of Valence Electrons for an Element, 02:42, Wayne Breslyn, 788,801, 2013-05-26T20:52:43.000000Z, 19, , , , , , 0, name-an-element-in-the-fourth-period-of-the-periodic-table-with-5-valence-electrons, Género de canciones de R&B

An explanation and practice for finding the number of valence electrons for elements on the periodic table. This is a key first step for drawing Lewis dot structures for molecules.

Looking at the Periodic Table, atoms have a regularly occurring number of valence electrons based on their Group number.

Group 1: One Valence Electron
Group 2: Two Valence Electrons
Group 13 (also called 3A): Three Valence Electrons
Group 14 (also called 4A): Four Valence Electrons
Group 15 (also called 5A): Five Valence Electrons
Group 16 (also called 6A): Six Valence Electrons
Group 17 (also called 7A): Seven Valence Electrons
Group 18 (also called 8A): Eight Valence Electrons*

* Although in Group 18, the element Helium only has two valence electrons.

In general we do not draw Lewis Structures for atoms of the Transition Metals (Groups 3-12).
