How to draw Lewis structures for polyatomic ion - Dr K

Be sure include the ionic charge in your calculation.

Correct, the total number must include the two electrons due to the ionic charge.

Recall that a negative charge is obtained by gaining electrons rather than losing them,

Be sure that you have included the valence electrons from all 5 of the atoms in this ion.

 Determine the total number of valence electrons in each atom in the polyatomic ion and adjust this number for the charge on the ion. 

How many valence electrons should be used in the Lewis structure for the polyatomic ion SO43&#8722;?

Draw the Lewis Dot Structure for calcium cyanide, Ca(CN)2.

Some theories of aging suggest that free radicals cause certain 
diseases and perhaps aging in general. As you know from the 
Lewis model, such molecules are not chemically stable and will 
quickly react with other molecules. According to certain theories, 
free radicals may attack molecules within the cell, such as 
DNA, changing them and causing cancer or other diseases. Free 
radicals may also attack molecules on the surfaces of cells, making 
them appear foreign to the body’s immune system. The immune 
system then attacks the cells and destroys them, 
weakening the body. Draw Lewis structures for each free radical 
implicated in this theory of aging.

Lewis Dot Structures: Neutral Compounds

Lewis Dot Structures or Electron Dot Structures&nbsp;are diagrams that show how elements in a molecule use their valence electrons to form bonds.&nbsp;

Average Bond Order

Average Bond Order represents the average number of chemical bonds between a pair of bond elements.

Lewis Dot Structures of Ions involves losing or gaining valence electrons to draw the most likely structure.&nbsp;

Octet Rule

The&nbsp;Octet Rule states that main-group elements will generally form enough bonds to obtain 8 electrons in their valence shell.&nbsp;

Lewis Dot Symbols

Lewis Dot Symbols represent the outer shell electrons of an element.&nbsp;

Lewis Dot Structures: Sigma & Pi Bonds

Sigma Bonds directly connect element together, while Pi Bonds provide insulation and protection for those bonds.&nbsp;

Lewis Dot Structures: Exceptions

Lewis Dot Structure Exceptions&nbsp;happen when the central element violates the Octet Rule.

Born Haber Cycle

In the Born-Haber Cycle, ionic solids are created through the ionization and eventual combination of elements.&nbsp;

Coulomb's Law

Coulomb's Law is used to determine the forces experienced by charged particles.&nbsp;

Chemical Bonds

A chemical bond is the connection&nbsp;of different elements through the sharing, transferring or pooling of electrons.&nbsp;

Resonance Structures

Resonance Structures are used to represent the different possible bonding arrangements of a molecule.

Lewis Dot Structures: Acids

Drawing the Lewis Dot Structure of Acids&nbsp;involves first drawing the polyatomic anion and then attaching the H+ ion.&nbsp;

Formal Charge

Formal Charge is the charge given to an element within a molecule when assuming equal sharing of electrons between bonded elements.&nbsp;

Bond Energy

Bond Energy is the amount of energy stored within a chemical bond.

Lattice Energy

Lattice Energy&nbsp;is the estimate for the strength of ionic bonds.&nbsp;

Dipole Moment

Dipole arrows are used anytime a molecule possesses a dipole moment, which happens when a molecule is polar.&nbsp;
