Binary Covalent Compounds
• Covalent compounds are those formed between elements that are both nonmetals both elements are to the right of
the staircase
• Use prefixes to tell how many atoms there are of each element because it is a covalent bond
(sharing electrons), there are no charges to work with

Binary Covalent Compounds
• The least electronegative one is listed first the element further to the left is listed first
• First element uses the name of the element
• Second element uses the name with the end changed to –ide
• Do NOT use mono- on the first element

Compounds with Added Water
• Some ionic compounds have water molecules as part of their structure. These compounds are called hydrates.
• A hydrate is a compound that has water chemically attached to its ions and written into its chemical formula. The water is like a body guard; it is attached to the
molecule and stays with it
• A compound is said to be hydrated if it contains water.

Compounds with Added Water
• When writing a formula that contains a hydrate, the number of water molecules is shown after a dot (∙). Following the dot a number indicates how many water molecules are attached.
• The same prefixes are used when naming hydrates. • The main ionic compound is named the regular way,
but the number of water molecules in the hydrate is indicated by the prefix.
• The above substance is called Calcium Sulfate Dihydrate.

Compounds with Added Water
• When a solution of cobalt(II) chloride evaporates, pink crystals that contain six water molecules for each unit of cobalt chloride are formed. What is the formula?
CoCl2 • 6 H2O

Compounds without Added Water
• The water from a hydrate can be removed. When this happens it is now considered anhydrous.
• An anhydrous is a compound without water.
