Ionic compounds tend to have high melting and boiling points, because the attraction between ions in the lattice is very strong. Moving ions out of the lattice disrupts the structure, so ionic compounds tend to be brittle rather than malleable.

Answer Expert Verified. Answer: Difference in properties of these two compounds are because one compound is covalent and the other one is ionic. Explanation: LiCl is an inorganic compound having high electronegativity difference between the two elements and hence, is termed as an ionic compound.

In ionic compounds, electrons are tightly held by the ions, and the ions cannot move translationally relative to each other. This explains many properties of ionic solids. They are hard and brittle, they are not malleable or ductile (i.e. cannot be shaped without cracking/breaking), and they do not conduct electricity.

Compounds that contain covalent bonds exhibit different physical properties than ionic compounds. Because the attraction between molecules, which are electrically neutral, is weaker than that between electrically charged ions, covalent compounds generally have much lower melting and boiling points than ionic compounds.

Physical properties are used to observe and describe matter.', 'Physical properties include: appearance, texture, color, odor, melting point, boiling point, density, solubility, polarity, and many others.']

Ionic compounds are made up of molecules as well. Ionic compounds have all the characteristics of a compound. ... The bond that holds the atoms together in it is ionic bond; electrostatic force of attraction. Ionic compounds have 2 or more ions joined together by means of ionic bond into molecules.

Ionic compounds typically have high melting and boiling points, and are hard and brittle. As solids they are almost always electrically insulating, but when melted or dissolved they become highly conductive, because the ions are mobilized.

Characteristics such as melting point, boiling point, density, solubility, color, odor, etc. are physical properties. ... Reactions of a substance, either with itself or with another substance are chemical properties. Physical and chemical properties can be used to classify a substance as ionic or molecular.

Ionic compounds have an equal number of positive and negative ions arranged in the three-dimensional lattice due to which they have high melting points. The strong force of attraction between oppositely charged ions means that ionic compounds have high melting and boiling points.

Ionic compounds are compounds consisting of ions. Two-element compounds are usually ionic when one element is a metal and the other is a non-metal. Examples include: sodium chloride: NaCl, with Na+ and Cl- ions. ... magnesium oxide: MgO, with Mg2+ and O2- ions.

In order for a compound to be considered an ionic compound (remember that all compounds have both ionic and covalent properties) the difference in electronegativity must be greater than 2. For BeBr2, this condition is not met. (Side note: BeBr2 is a nonpolar molecule as well).

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.
