Question:
What is the chemical formula of trisilicon tetranitride? A. Si3N4 B. Si4N3 C. Si3N6 D. Si6N3 E. Si4N6 Reset Next
Answer:
Answer : The correct option is, (A)
Explanation :
Trisilicon tetranitride is a covalent compound because sharing of electrons takes place between silicon and nitrogen. Both the elements are non-metals and hence, will form a covalent bond.
The formula of covalent compound is given by :
The less electronegative element is written first.
The more electronegative element is written next.
If atoms of an element is greater than 1 that means their prefixes are written in the respective element’s subscript.
As per given name of compound, the less electronegative element is ‘Si’ and more electronegative element is ‘N’.
So, the chemical formula of trisilicon tetranitride is,
