ionic compounds are generally volatile in nature?????
Answers
Answer:
Ionic compounds are basically defined as being compounds where two or more ions are held next to each other by electrical attraction. One of the ions has a positive charge (called a "cation") and the other has a negative charge ("anion"). Cations are usually metal atoms and anions are either nonmetals or polyatomic ions (ions with more than one atom).
Properties of ionic compounds:
High melting and boiling points - Ionic bonds are very strong - a lot of energy is needed to break them. So ionic compounds have high melting and boiling points.
Conductive when liquid - Ions are charged particles, but ionic compounds can only conduct electricity if their ions are free to move. Ionic compounds do not conduct electricity when they are solid - only when dissolved in water or melted.
Ionic materials are non-molecular materials, and consist of infinite arrays of close-packed ions held together by strong electrostatic bonds.and these typically exhibit high melting points
But on the other hand, covalently-bound materials can ALSO be non-molecular and consist of infinite arrays of covalently bound atoms And we look at silicon dioxide, or graphite, or diamond, and the bonding between ATOMS is certainly covalent, however, this covalent bonding extends across the entire lattice, with the result that these materials exhibit exceptionally high melting, and boiling points, in some instances GREATER than those of ionic salts
On the other, other hand, SOME covalently bound materials can be MOLECULAR, and the forces of intermolecular interaction can be LOW to modest and for example, dinitrogen, methane, ethyl alcohol, water as intermolecular interaction becomes greater, i.e. with the possibility of intermolecular hydrogen-bonding in water, and alcohol, the boiling points INCREASE.
