Answer:
Silicon is a metalloid.
physical properties :
* Silicon has a metallic lustre.
* brittle in nature.
*semiconductors.
Chemical properties :
* Atomic number is 14. So Silicon has a total of four electrons in its outermost shell.
* Silicon is known to be a p-block element. Its electronic configuration is given by [Ne]3s23p2.
* Silicon is very reactive at higher temperature.
Step-by-step explanation:
silicon is classified as a metalloid because some of its properties resemble the properties of metals and some of its properties resemble those of nonmetals.
