An ionic bond forms when
A
Valence electrons are shared
B
a sea of mobile electrons surround the cations
C
valence electrons are transferred between atoms
D
none of the above
Explanation: 

Detailed explanation-1: -ionic bond, also called electrovalent bond, type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound. Such a bond forms when the valence (outermost) electrons of one atom are transferred permanently to another atom.

Detailed explanation-2: -Ionic bonding Definition: An ionic bond is formed when valence electrons are transferred from one atom to the other to complete the outer electron shell. Example: A typical ionically bonded material is NaCl (Salt): The sodium (Na) atom gives up its valence electron to complete the outer shell of the chlorine (Cl) atom.

Detailed explanation-3: -An ionic bond is formed by the complete transfer of some electrons from one atom to another. The atom losing one or more electrons becomes a cation-a positively charged ion. The atom gaining one or more electron becomes an anion-a negatively charged ion.

Detailed explanation-4: -An ionic bond is the force of attraction that holds together positive and negative ions. It often forms when atoms of a metallic element give up electrons to atoms of a nonmetallic element. Ionic bonds form only between metals and nonmetals.

Detailed explanation-5: -The opposite charges on the ions cause the ions to bond, or be held together, by electrostatic forces. An ionic bond is a bond between ions where oppositely charged atoms attract each other and cancel their charges to produce neutral compounds.
