What type of solid is iodine?
molecular solid
Is I2 ionic or covalent?
Iodine forms a diatomic non-polar covalent molecule. The graphic on the top left shows that iodine has 7 electrons in the outer shell. Since 8 electrons are needed for an octet, two iodine atoms EQUALLY share 2 electrons.
Is Silicon a covalent solid?
A covalent network structure consists of a giant 3-dimensional lattice of covalently bonded atoms. Boron, carbon and silicon are all examples of covalent network elements. Diamond and graphite, two forms of carbon and compounds like silicon dioxide and silicon carbide are all covalent networks.
Which type of solid tends to be the hardest?
Most covalent network solids are very hard, as exemplified by diamond, which is the hardest known substance. Covalent network solids have high melting points by virtue of their network of covalent bonds, all of which would have to be broken for them to transform into a liquid.
What type of solid is co?
Properties of Solids
| Table 1. Types of Crystalline Solids and Their Properties | ||
|---|---|---|
| Type of Solid | Type of Particles | Examples |
| metallic | atoms of electropositive elements | Cu, Fe, Ti, Pb, U |
| covalent network | atoms of electronegative elements | C (diamond), SiO2, SiC |
| molecular | molecules (or atoms) | H2O, CO2, I2, C12H22O11 |
What are the three types of solid?
There are two main categories of solids: crystalline and amorphous. Crystalline solids are well ordered at the atomic level, and amorphous solids are disordered. There are four different types of crystalline solids: molecular solids, network solids, ionic solids, and metallic solids.
What is the only property of liquid?
A liquid is a nearly incompressible fluid that conforms to the shape of its container but retains a (nearly) constant volume independent of pressure. As such, it is one of the four fundamental states of matter (the others being solid, gas, and plasma), and is the only state with a definite volume but no fixed shape.
