A
mole
B
ion
C
molecule
D
bond
Explanation: 

Detailed explanation-1: -When an atom loses or gains an electron, ions are formed. If an atom loses electron it forms positive charge and if gains electron it forms negative charge. An atom which carries charge on it is known as ion.

Detailed explanation-2: -If an atom or molecule gains an electron, it becomes negatively charged (an anion), and if it loses an electron, it becomes positively charged (a cation). Energy may be lost or gained in the formation of an ion.

Detailed explanation-3: -When an atom gains electrons it is called an Anion.

Detailed explanation-4: -Atoms that lose electrons acquire a positive charge as a result because they are left with fewer negatively charged electrons to balance the positive charges of the protons in the nucleus. Positively charged ions are called cations.
