Which terms describe two atoms when they form a bond in which electrons are completely transferred from one atom to the other?

Ionic bonding

Explanation:

Ionic bonding:-

This type of bonding is formed when there is a complete transfer of electrons from one element to another element. In this bonding one element is always a metal and another is a non-metal.

For example, Calcium iodide

Calcium is the element of second group and forth period. The electronic configuration of Calcium is - 2, 8, 8, 2 or

There are 2 valence electrons of Calcium.

Iodine is the element of seventeenth group and fifth period. The electronic configuration of Iodine is - 2, 8, 18, 18, 7 or

There are 7 valence electrons of iodine.

Calcium iodide, is formed when 2 valence electrons of calcium are loosed and they are gained by 2 atoms of iodine.
