In network of silica (Si02), each silicon atom is surrounded by of oxygen
Correct answer: A. 4
- A. 4
- B. 2
- C. 1
- D. 6
Explanation
In the network of silica (SiO2), each silicon atom is surrounded by (a) 4 oxygen atoms.Therefore, remembering the basic stoichiometry of SiO2 (1 silicon to 2 oxygen atoms) and considering the need for silicon to fulfill its octet rule helps in determining the correct answer.

About Transition Elements
Transition elements are identified by their partially filled d subshells in atoms or common ions. The topic covers the electronic structure of d-block elements, including the filling order of 4s and 3d orbitals, variable oxidation states and the distinction between transition elements and elements with completely filled d subshells.
