Question

How is an ionic bond formed?
An electron is transferred from one atom to another.
Two atoms share the electrons in their outermost shells.
Both atoms in the bond lose an electron.
Both atoms in the bond gain an electron.

Answer 1

an electron is transferred from an electron to the other

Answer 2

Answer:

An electron is transferred from one atom to another.

Explanation:

Ionic bonds are formed between cations and anions. When an electronegative atom gains an electron from an electropositive atom, the former becomes negatively charged anion while the later atom acquires a positive charge and is called cation.

The opposite charges of anion and cation attract each other and join them by an ionic bond. Example: Na+ and Cl- ions are bonded together by ionic bond and form NaCl.
