Question

trivalent and tetravalent elements

Answer 1

Explanation:

An atom having three covalent bonds. In this molecule the hydrogen atom and chlorine atoms are monovalent, the oxygen atom is divalent, the nitrogen atom is trivalent, and the carbon atom is tetravalent.

Tetravalent elements are those elements which have a valency of four i.e. have four electrons in the outermost shell. Some examples are the elements belonging to group 14 like carbon, silicon, germanium etc.

Answer 2

Answer:

Trivalent ions :- in this atom having three covalent bonds. In this molecule the hydrogen atom and chlorine atoms are monovalent, the oxygen atom is divalent, the nitrogen atom is trivalent, and the carbon atom is tetravalent.

Tetravelent ions:-Tetravalent ions are those ions which have a valency of four i.e. have four electrons in the outermost shell. Some examples are the elements belonging to group 14 like carbon, silicon, germanium etc.
