The correct answer is A, ionic bonds.
Explicación
## Step 1The problem is asking us to identify the type of bond that forms when atoms gain or lose electrons. This is a characteristic of ionic bonds.## Step 2Ionic bonds occur when one atom donates an electron to another atom. This results in the formation of positively charged ions (cation) and negatively charged ions (anion). The positive and negative charges of the ions attract each other, forming an ionic bond.## Step 3Covalent bonds, on the other hand, involve the sharing of electrons between atoms. This is not the case in the problem, as the problem specifies that electrons are gained or lost, not shared.## Step 4Metallic bonds involve a 'ea' of delocalized electrons that are free to move around. This is also not the case in the problem, as the problem specifies that electrons are gained or lost, not delocalized.## Step 5Polyatomic bonds refer to molecules that consist of more than two atoms. This is not the case in the problem, as the problem specifies that electrons are gained or lost, not the number of atoms in a molecule.
