Question

tetravalent element with their chemical formula and symbols...​

Answer 1

Answer:

The word ‘tetra’ means four while the world ‘valency’ means the number of electrons gained or lost so that an atom can successfully bond with another and become a stable element

So essentially, tetravalency refers to the capacity of an atom to form four stable bonds around it, and this is generally observed with carbon but also a couple of other elements like silicon etc.

Explanation:

For example, let’s consider the chemical compound Methane (CH4).

In the compound CH4, one carbon atom forms four stable bonds with four hydrogen atoms hence making it a tetravalent compound

Answer 2

Answer:

Carbon ( C) and Silicon (Si) are tetravalent.

Explanation:

Tetra-4 ; Valent - Valency.

The elements having 4 valence electrons are called tetravalent elements.
