Giant Covalent Structures Flashcards
To learn about them
What are giant covalent structures?
Consists of many non-metal atoms joined by covalent bonding and arranged in a repeating regular pattern.
Explain why diamonds can be described as having a giant lattice structure?
Because carbon is joined to 4 other carbon atoms by covalent bonds.
Explain why the formula of silica SiO2 suggests. Suggests what info is missing from the diagram and justify your answer.
Each oxygen (o) atom is bonded to two silica(Si) atoms.
Metals are shiny in apperance.
Money metals are usually dull
Metals usually have high melting points
Non metals have low melting points
Most metals are solid state at room temperature,one non metal is liquid at room temp, about half are solid state, and the rest are in the gas state.
Metals are malleable and ductile.
Non metals are brittle in solid state.
Metals are usually good conductor of heat and electricity
Non metals are insulators.
