Two elements having valency 4.
Answer:
Two elements having valency four are 14Si (silicon) and 6C (carbon)
Explanation:
⇒ The atomic number of carbon = 6
The electronic configuration of 6C = 2,4
The electrons in the outermost shell = 4
Thus, its valency is 4.
⇒ The atomic number of silicon = 14
The electronic configuration of 14Si = 2,8,4
The electrons in the outermost shell = 4
Thus, its valency is 4
