Are silicon compounds ionic or covalent?
They are covalent. Some are simple molecules, others are giant covalent structures.
What is a giant covalent lattice?
Giant covalent, lattice structures contain a lot of non-metal atoms, each joined to adjacent atoms by covalent bonds. The atoms are usually arranged into giant regular lattices. The structure requires an element with very strong bonds between the atoms to create various materials. A couple of examples are (carbon) Diamond and Buckminster Fullerine. Graphite is also one but has weak bonds as well. Silica and molybdenum can also make covalent lattice structures.
Does covalent structures have high or low boiling points?
It depends on the type of structure; simple covalent structures (like water) generally have low boiling points, while giant covalent structures (like diamond) have high boiling points.
What following types of compound can form giant structures ionic covalent metal?
the answer is 3
Why are giant covalent structures non conductors of electricity?
because there're no mobile ions

Why does silicon can form giant structures?
Silicon (like carbon) can form covalent bonds, it forms a giant molecule with the diamond structure. Silicon dioxide is also a giant structure with polar covalent bonds. Silica reacts with basic oxides to form silicates- and these are generally giant structures, polar covalent bonds again, that form a very large proportion of the minerals in the earths crust.
Can carbon form covalent bonds with other carbon atoms?
Indeed they can. A common example of Carbon covalently bonding with carbon is in what we refer to as Giant Covalent Structures, which are multiple of an atom bonded together in a set, lattice-like shape. Examples of giant covalent structures made from carbon are diamond where the atoms are arranged in a pyramid shape, and graphite, where they are arranged in flat layers.
what type of bonds form lattice structures?
Ionic bonded always. Also giant covalent structures- like diamond and silicon dioxide. It is NOT just ionic compounds!
Can giant covalent structures conduct electricity when molten?
Some do- for example molten silicon conducts like ametal when molten.
Why do metals giant covalent structures not conduct electricity?
Because there are no free electrons. However, graphite does conduct electricity as there are free electrons.
