WebIdentify the following substances as ionic, metallic, covalent network, or molecular solids: Substance A is malleable, ductile, conducts electricity well, and has a melting point of 1135 °C. Substance B is brittle, does not … WebCovalent network solids are hard/brittle. Covalent bonds are very strong and difficult to break, which causes this hardness. Diamonds, one of the strongest substances on earth, can withstand 6 million atmospheres. Those are some strong bonds! ... an ionic bond is formed between ...

WebJul 23, 2014 · They are very hard, somewhat brittle solids with extremely high melting points (higher than 1,000 C or 1,800 F). Unlike ionic compounds, they do not dissolve in water, nor do they conduct electricity. WebThe breakage of covalent sigma bonds can cause distortion away from this geometry. As a result, covalent solids have a very high melting point. They’re usually exceedingly hard materials that will shatter rather than alter shape smoothly. Hence, they are rigid and brittle. And diamond and silica are examples of covalent solids. ge water heater warranty period

WebNov 3, 2024 · They are very hard and brittle; They have very high melting and boiling point. They are non-volatile compounds. They are soluble in polar solvent (like H 2 O). Their ions are not free to move in solid state, so they are insulators of electricity but in molten or aqueous solution their ions free to move so become good conductor of electricity. WebNov 16, 2024 · Generally, ionic crystals form from a combination of Group 1 or 2 metals and Group 16 or 17 nonmetals or nonmetallic polyatomic ions. Ionic crystals are hard and brittle and have high melting points. Ionic compounds do not conduct electricity as solids, but do conduct electricity when molten or in aqueous solution.
