Some physical properties of silicon are that it is dark gray in color, its phase is a solid, and has a metallic shine. Its boiling point is 2600 degrees Celsius. The physical properties of an element or substance are those that we can examine with our senses. These properties include melting point, hardness, conductivity, and density.
Some chemical properties of the silicon are:
- atomic number: 14
- atomic weight: [28,084; 28,086]
- place in the Periodic Table: group 14, period 3
- element category: metalloid
- electronegativity: 1,9 (after L. Pauling table) - an element not so reactive
- typical valence: 4
- react with halogens
- don't react with acids (an exception HF)
silicon is a shiny silvery solid it has a diaond like structure, the Si-Si bond is weaker than C-C bond , therefore the meltinf and boiling points are lower as compared to carbon.it is stable upto 1710 degree C

No silicon is an element in the same group as carbon, it has similar chemical properties but it is not carbon.
It is a metalloid, it has both metallic and non-metallic properties.
How reactive is the element silicon?
is silicon a mixture? Silicon is a pure substance because it is an element.
No. Silicon is a metalloid.
Silicon.
The element with chemical properties most like silicon is germanium. As an example, both are used in semiconductors.
No silicon is an element in the same group as carbon, it has similar chemical properties but it is not carbon.
Silicon.
Silicon, which is just below carbon, and Germanium are the two elements that are most like carbon.
Silicone materials are partly made of the element silicon, but most or all the silicon atoms in them are also bonded to oxygen atoms. Therefore, silicone materials do not have the chemical properties of pure elemental silicon.
It is a metalloid, it has both metallic and non-metallic properties.
