A chemical bond formed by complete transfer of electrons is called:

  1. Ionic
  2. Covalent
  3. Coordinate
  4. Metallic
Show answer and solution

Correct answer: A. Ionic

1. Ionic bonds form when a metal donates electrons to a non-metal. 2. The donor becomes a positive ion (cation). 3. The acceptor becomes a negative ion (anion). 4. The opposite charges attract, holding the ions together. _Source: Selina Concise Chemistry ICSE Class 10, Ch 2 'Chemical Bonding'_
