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.
What else can I help you with?
Can giant covalent structures conduct electricity when molten?
Yes, giant covalent structures can conduct electricity when molten because the atoms are free to move and carry charge. This allows for the formation of a continuous pathway for the flow of electricity. Examples of giant covalent structures that can conduct electricity when molten include graphite and silicon.
Does silicon oxide have a simple molecular or giant structure?
Silicon oxide has a giant molecular structure, with each silicon atom bonded to four oxygen atoms in a tetrahedral arrangement. This structure forms a network of interconnected silicon and oxygen atoms, giving silicon oxide its solid and rigid properties.
Silicon dioxide diamond covalent network?
Silicon dioxide and diamond are both examples of covalent network structures in which each atom is covalently bonded to its neighboring atoms. This results in strong, rigid structures with high melting and boiling points. Silicon dioxide forms a crystalline structure in the form of quartz or sand, while diamond is a unique form of carbon arranged in a tetrahedral lattice.
Which is not true of a single silicon-oxygen tetrahedron?
A single silicon-oxygen tetrahedron is typically not stable on its own and tends to polymerize or form interconnected structures with other tetrahedra. They are the building blocks of various silicate minerals and have a net charge of -4. Silicon-oxygen tetrahedra are not found in isolation but are connected to form complex networks in minerals.
If silicon bonded with three oxygen atoms how might the crystalline structures of silicate minerals?
If silicon is bonded to three oxygen atoms, it will form a silicate tetrahedron. Silicate minerals can have different crystalline structures depending on how these tetrahedra are arranged, such as in chains, sheets, or three-dimensional networks. This arrangement determines the physical properties of the mineral.
What following types of compound can form giant structures ionic covalent metal?
Ionic compounds can form giant structures, such as ionic lattices, due to the attraction between positively and negatively charged ions. Similarly, covalent compounds, like diamond or silicon dioxide, can form giant structures through the sharing of electrons between atoms. Metal compounds can also form giant structures, known as metallic lattices, due to the delocalization of electrons among metal atoms.
Can giant covalent structures conduct electricity when molten?
Yes, giant covalent structures can conduct electricity when molten because the atoms are free to move and carry charge. This allows for the formation of a continuous pathway for the flow of electricity. Examples of giant covalent structures that can conduct electricity when molten include graphite and silicon.
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 Silicon form a covalent bond?
Yes, silicon can form covalent bonds. It commonly forms covalent bonds with other silicon atoms in crystalline structures like silicon dioxide (SiO2) and inorganic compounds.
When atoms join by covalent bonds they form?
giant molecoule structures
Why are giant covalent structures non conductors of electricity?
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.
Does silicon oxide have a simple molecular or giant structure?
Silicon oxide has a giant molecular structure, with each silicon atom bonded to four oxygen atoms in a tetrahedral arrangement. This structure forms a network of interconnected silicon and oxygen atoms, giving silicon oxide its solid and rigid properties.

Which is not true of a single silicon- oxygen tetrahedron?
It has four silicon atoms.
Is silicon dioxide a giant or simple structure?
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.
Is silicon giant or simple?
Silicon is a chemical element known for its unique properties. In its natural state, it forms a giant molecular structure, with each silicon atom bonded to four others in a tetrahedral arrangement, making it a giant covalent structure. This gives silicon its characteristic hardness and strength.
