silicon (IV) oxide or silicon dioxide has giant covalent structure
it is a simple structure
Calcium Chloride is a giant structure
phosphorus has weak inter molecular forces(vander waals) between molecules,where as silicon has giant structure,so it has strong bonds .....takes more energy to break bonds,so higher bp and mp
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.
yes, it is bonded in a giant covalent lattice and has a tetrahedral structure, and is very hard to break apart
Sand has a giant molecular structure. It is mainly made of a mineral called quartz, which is silicon oxide (SiO2).
giant
Such compounds can have either a giant or a simple molecular structure. Cellulose is an example of a material with a giant structure, and carbon monoxide has a very simple one.
Carbon and Silicon.
simple molecular compounds have weak forces of atraction.
it is a simple structure
it is a simple structure
That's a very good question and there are arguments for both. I would class it more as a simple molecular substance because a sample will contain many separate molecules, with forces other than covalent bonds between them. A giant covalent structure like diamond is wholly held together by covalent bonds.

Magnesium Bromide has a giant structure
