Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
When oppositely charged atoms are attracted to each other
A
Ionic bond
B
Polar covalent bond
C
Nonpolar covalent bond
D
None of the above
Explanation: 

Detailed explanation-1: -Ions with opposite charges will attract one another creating an ionic bond. Such bonds are stronger than hydrogen bonds, but similar in strength to covalent bonds. In an ionic bond, the atoms are bound by attraction of opposite ions, whereas in a covalent bond, atoms are bound by sharing electrons.

Detailed explanation-2: -Ionic bonding is the attraction between positively-and negatively-charged ions. These oppositely charged ions attract each other to form ionic networks (or lattices). Electrostatics explains why this happens: opposite charges attract and like charges repel.

Detailed explanation-3: -The attraction between oppositely charged ions is called an ionic bond, and it is one of the main types of chemical bonds in chemistry. Ionic bonds are caused by electrons transferring from one atom to another. In electron transfer, the number of electrons lost must equal the number of electrons gained.

Detailed explanation-4: -The ionic bond is the electrostatic force of attraction between a positively charged metal ion and a negatively charged non-metal ion. Metals form positive ions because they lose electrons to become stable.

Detailed explanation-5: -In an ionic bond, the two oppositely charged ions are held together by strong electrostatic force of attraction.
