Type of bonding in Sodium (Na) is:
Correct answer: A. Metallic
- A. Metallic
- B. Ionic
- C. Covalent
- D. Coordinate Covalent
Explanation
The type of bonding in Sodium (Na) is metallic (Option A). 'Metallic bonding' implies the presence of an attractive force between delocalized electrons, initially present in the outermost orbit of the metal atoms, and positively charged metal cations. All metals possess this type of bond. An 'Ionic bond' is formed between a positively charged metal ion and a negatively charged nonmetal ion. A 'Covalent bond' is usually formed between two non-metals. Sodium does not possess a 'coordinate covalent bond' in between its atoms so, all the options are incorrect except Option A.

About Chemical Bonding
Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
