![]() ![]() Periods are indicated by a number, 1, 2, 3, etc. Properties are also consistent across the rows, or periods. All elements in Group II have two (2) valence electrons, all the way up to VIII, eight (8) valence electrons. For example, all elements which fall within the first column, or Group I, have one (1) valence electron. Each Group, or column, is indicated by a roman numeral which represents the number of valence electrons. The periodic table has all of the information needed to draw a Lewis dot structure. ![]() Using the Periodic Table to Draw Lewis Dot Structures A Lewis Dot Structure can be made for a single atom, a covalent compound, or a polyatomic ion. Lewis structures are drawn by a series of dots, lines, and atomic symbols and provide a structure for the way that the atom or molecule is arranged. Keep in mind that in reality electrons are constantly moving around the nucleus and are not rooted in one place as portrayed in a 2D structure. These valence electrons are negatively charged and are attracted to the positively charged nucleus, made up of neutrons and protons. Lewis Dot Structures, or Lewis Structures for short, are visuals that represent the outermost shell of electrons, also known as valence electrons, and possible covalent bonds within an atom or molecule. Not even under a complex microscopic can we view the individual electrons that surround an atom’s nuclei. The only thing smaller than atoms is their subatomic particles electrons, protons, and neutrons. ![]() Drawing Lewis Dot Structures for Polyatomic Ions.Examples for Drawing Lewis Structures for Covalent Bonds.Using Lewis Structures to Show Valence Electrons.Using the Periodic Table to Draw Lewis Dot Structures. ![]()
