What type of bond is formed between an atom that has lost an electron and an atom that has gained an electron?
A
covalent
B
hydrogen
C
van der Waal
D
ionic
Explanation: 

Detailed explanation-1: -An ionic bond can be formed after two or more atoms loss or gain electrons to form an ion. Ionic bonds occur between metals, losing electrons, and nonmetals, gaining electrons. Ions with opposite charges will attract one another creating an ionic bond.

Detailed explanation-2: -Ionic bonds are formed by one atom losing an electron to be positive and another atom gaining one to be negative whereas a covalent bond is formed by two atoms sharing the valence electrons of each other. How are ionic bonds and covalent bonds different?

Detailed explanation-3: -There are primarily two forms of bonding that an atom can participate in: Covalent and Ionic. Covalent bonding involves the sharing of electrons between two or more atoms. Ionic bonds form when two or more ions come together and are held together by charge differences.

Detailed explanation-4: -Thus, the term “ionic bonding” is given when the ionic character is greater than the covalent character – that is, a bond in which there is a large difference in electronegativity between the two atoms, causing the bonding to be more polar (ionic) than in covalent bonding where electrons are shared more equally.

Detailed explanation-5: -ionic bond, also called electrovalent bond, type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound. Such a bond forms when the valence (outermost) electrons of one atom are transferred permanently to another atom.
