Ionic solids—Made up of positive and negative ions and held together by electrostatic attractions. They're characterized by very high melting points and brittleness and are poor conductors in the solid state.

The cations and anions being oppositely charged attract each other through strong coloumbic forces and form an ionic bond. Properties of ionic compounds: 1) They are hard and crystalline due to regular arrangement of ions. 2) They have high melting points due to strong electrostatic attractions.

Ionic compounds have high melting and boiling points, so they are in the solid state at room temperature. See the study guide on the three states of matter to see how bonding and structure are related to the properties of substances. Energy must be transferred to a substance to make it melt or boil.

Ionic compounds tend to have higher melting and boiling points than covalent compounds. Ionic compounds tend to be hard and brittle while covalent compounds tend to be softer and more flexible. Ionic compounds conduct electricity when dissolved in water while covalent compounds typically don't.
358432
Ions form when atoms lose or gain electrons. Ionic compounds have positive ions and negative ions. Ionic formulas balance the total positive and negative charges. Ionic compounds have a simple system of naming.

In ionic compounds, electrons are tightly held by the ions, and the ions cannot move translationally relative to each other. ... The 'free valence electrons' model explains several properties of metals: they conduct electricity, are malleable and ductile (can have their shape changed without breaking) and are not volatile.

Ionic compounds have ionic bonds and molecular compounds have covalent bonds. ... Ionic compounds have higher melting and boiling points compared to molecular compounds. Ionic compounds conduct electricity in their molten state and in their aqueous solutions. Molecular compounds are poor conductors of heat and electricity.

Some of the properties of ionic solids are high melting point, low vapor pressure, brittleness and the inability to conduct electricity. Ionic compounds can be readily dissolved by polar molecules like water.
