+ High melting and boiling points
+ Insoluble in water and organic solvents
+ Do not conduct electricity (except when they have free electrons eg graphite)
+ Solid at room temperature
No, argon does not have a giant covalent structure. Argon is a noble gas that exists as individual atoms rather than forming covalent bonds with other atoms to create a giant structure.
No, wax is not a giant covalent structure. Wax is composed of long-chain hydrocarbons and does not have a complex molecular structure like giant covalent substances such as diamond or graphite.
Well, you've mystified me. I have a PhD in chemistry, and this is the first I've ever heard of a "giant ionic and covalent structure". Could you try being a little more specific? I can think of materials that might qualify ... zeolites, for example, which are partly ionic and partly covalent and might form extensive networks ... but these are compounds, not elements.
No, wax contains very large molecules.
No, water is not a giant covalent structure. Water molecules are held together by hydrogen bonds, which are much weaker than the covalent bonds typically found in giant covalent structures like diamond or graphite.
The giant structure involve an enormous number of atoms.

No, iodine does not have a giant covalent structure. Iodine exists as diatomic molecules (I2) held together by weak van der Waals forces. Each iodine atom forms covalent bonds with one another within the I2 molecule.
Substances that usually contain covalent bonds have a simple molecular structure. Examples include elements like oxygen and compounds like methane. Giant molecular structures are typically found in substances with strong covalent bonds, such as diamond and quartz.
Silicon dioxide has a giant molecular structure, also known as a giant covalent structure. Each silicon atom is covalently bonded to four oxygen atoms in a three-dimensional network, creating a large and interconnected structure.
A lattice in giant covalent bonding refers to the arrangement of atoms in a three-dimensional structure where each atom is bonded to its neighboring atoms through strong covalent bonds. This results in a spatially extended network of covalent bonds throughout the material, giving it unique structural and physical properties. Examples include diamond and graphite.
Giant covalent structures, such as diamond and silicon dioxide, have a strong network of covalent bonds that hold their atoms together in a rigid structure. These bonds do not allow for the movement of electrons, which is necessary for conducting electricity. Therefore, giant covalent structures are non-conductors of electricity.
