What are tetravalent elements???
“Tetra” means four and “valent” means valency.
So, an element is said to be tetravalent if it has a valency of four. These types of elements have four electrons in their valence shell, need four more to complete their octet and are capable of forming maximum four bonds. One such element is carbon. It can form four covalent bonds owing to its tetravalent nature. Another example is silicon, which also has four electrons in its valence shell.
hope u r clear now
hope it helps
