Two elements are more likely to be ionically bonded when ....
larisa86 [58]

Answer:

The correct option is: b. the elements in the material are well apart (in different sides) in the periodic table            

Explanation:

Ionic bond is a type of chemical bonding that is formed by the transfer of electrons from one atom to another. It is formed between atoms having large electronegativity difference.

The more electronegative atom accepts electrons and becomes a negatively charged anion. Whereas, the less electronegative atom loses electrons and becomes a positively charged cation.

<u>Simply, an ionic bond is formed when the electrons are transferred from a metal to a non-metal, which are present on different sides of the periodic table.</u>
