Chemical Bonding:Properties of Compounds

The vertical column of the periodic table is group.

Hydrogen is an example of metallic elements.

Ionic and covalent compounds can be identified and described through their chemical  formula and name by observing the types of elements involved in a compound.

At a normal atmospheric pressure and temperature,ionic compounds may exists in solid,liquid,or a gas, while covalent compounds exist only as crystalline solids.

Ionic compounds generally have higher melting and boiling points while covalent compounds have lower melting and boiling point.

Covalent compounds are hard and brittle,while ionic compounds are soft and flexible.

Ionic compounds have high polarity, while covalent compounds have low polarity.

Covalent compounds are less soluble in water,while ionic compounds are usually soluble in water.

Covalent compounds tend to be less flammable than ionic compounds.

Covalent compounds conduct heat and electricity compared to ionic compounds.

Compounds are made up of elements that are chemically bonded by _____________ forces.

Chemically bonded compounds can be classified into ionic or __________ compound.

In a compound, polarity results in the distribution of electrical charge over the atoms joined by the bond.Polarity of compounds depend on the___________ difference of elements involves.

Compounds that involves metal and nonmetal and has an electronegativity difference of greater than ______ results in an ionic compound.

____________ compounds conduct electricity, but not in solid phase.
