Answer:
The minimum number of electrons required to form trivalent bond between two atoms D.8
Explanation:
- Trivalent bond means an atom having three valence electrons.(three covalent bonds).
- It can also be stated as a bond formed between two atoms in which both the atoms has three valence electrons.
- Atom which has three valence electrons predominantly forms covalent bonds.
- examples of such trivalent atoms are nitrogen,aluminium etc.... especially thirteenth and fifteenth group elements.
- trivalent ion means an ion which on it's uppercase possess valence of three.
- The trivalent atom X which has a valency of -3 is called trivalent anion and that of +3 is called trivalent cation.
- a strongly hexahydrated trivalent ion may have a stronger second hydration shell than mono and di valent ions.
