What is an ionic substance? How is it named?
Two non-metals
Two metals
A metal ion and a non-metal ion
The subscript indicates the charge of the substance
The subscript indicates the number of atoms of each type that form the substance
The subscript indicates the location on the periodic table
Metals form positive cations. Example Na 1+
Metals form postiive anions. Example: Na 1+
Metals form negative anions. Example: Na1-
Each hydrogen ion has a charge of 1+. This will balance the charge of 2- from the one oxygen ion
Each hydrogen has a charge of 2+ and the oxygen has a charge of 1-
The two hydrogen molecules have a combined charge of 2+ and the oxygen has a charge of 1-
Salts are made up of two non-metals and form a covalent bond.
Salts are made up of a metal and non-metal and form an ionic bond.
An ionic bond is very strong and therefore the substance will have a high melting and boiling point.
An ionic bond is weak and will have a low melting and boiling point
