Chemical Bonds Quiz

Which type of chemical bond is characterized by the sharing of electrons between atoms?

• Ionic

• Covalent

• Metallic

• Hydrogen

What is the primary force that holds atoms together in a metallic bond?

• Electrostatic attraction between ions

• Sharing of electrons in localized bonds

• A "sea of electrons" surrounding nuclei

• Directional covalent interactions

What is the main type of attraction that occurs in an ionic bond?

• Covalent attraction

• Metallic bonding

• Van der Waals forces

• Electrostatic attraction between ions

Who developed a method to denote potential bonding electrons by using one dot for every valence electron around the element symbol?

• Dmitri Mendeleev

• Linus Pauling

• G. N. Lewis

• J. J. Thomson

According to the octet rule, when forming compounds, atoms tend to:

• Share electrons until they are surrounded by two valence electrons

• Share electrons until they are surrounded by eight valence electrons

• Lose all their valence electrons

• Gain a variable number of electrons depending on the element
