Example Question #1 : Chemistry

Which of the following types of chemical bonds is very strong and involves transfer of an electron between atoms?

Possible Answers:

Ionic bonds

Covalent bonds

Hydrogen bonds

Disulfide bonds

Correct answer:

Ionic bonds


There are two primary bond types: ionic bonds and covalent bonds. Ionic bonds involve the transfer of an electron between atoms, while covalent bonds require atoms to share an electron between them. Ionic bonds are the stronger of the two. Ionic bonds usually form between a metal and a non-metal (for example, NaCl), while covalent bonds usually form between two non-metals (for example, HCl).

Hydrogen bonds are a type of intermolecular force and are similar to a very weak covalent bond. Hydrogen bonds are not actual bonds, and do not chemically link atoms together; they are strictly physical interactions. Disulfide bonds are covalent bonds between sulfur atoms that help form protein structure.
