WebFor example, some covalent compounds, such as carbon, can have very high melting points if they have strong covalent bonds. Additionally, some ionic compounds, such as those with large or highly charged ions, can have relatively low melting points. One specific example is sodium chloride (NaCl), an ionic compound, which has a melting … WebThe ionic and covalent bonds of ceramics are responsible for many unique properties of these materials, such as high hardness, high melting points, low thermal expansion, and good chemical resistance, but also for some undesirable characteristics, foremost being brittleness, which leads to fractures unless the material is toughened by reinforcing …

Properties of ionic, covalent, and metallic compounds

WebMolecular compounds typically have low melting and boiling points because the attraction between molecules (which are electrically neutral) is weaker than that between electrically charged ions. Under normal conditions molecular compounds often exist as gases, liquids, or low-boiling solids. They do not conduct electricity or heat well. WebFor example, sodium chloride (NaCl) is an ionic compound that consists of a multitude of strong ionic bonds. Sodium chloride melts at 801°C. ... their soft bulk character, and their low melting points ... solid materials tend to keep their shape when undergoing thermal expansion.
