What is the main difference between ionic and covalent bonds?

• Ionic bonds involve the attraction between oppositely charged ions, while covalent bonds involve sharing electrons

• Ionic bonds involve sharing electrons, while covalent bonds involve transferring electrons

• Ionic bonds occur between non-metals, while covalent bonds occur between metals and non-metals

• Ionic bonds form crystal lattices, while covalent bonds form individual units

What is the result of an ionic bond between sodium and chlorine?

• Sodium becomes a negatively charged ion and chlorine becomes a positively charged ion

• Sodium and chlorine both become positively charged ions

• Sodium and chlorine both become negatively charged ions

What is the difference between a nonpolar covalent bond and a polar covalent bond?

• In a nonpolar covalent bond, electrons are shared unequally, while in a polar covalent bond, electrons are shared evenly

• In a nonpolar covalent bond, electrons are not shared, while in a polar covalent bond, electrons are shared

• In a nonpolar covalent bond, electrons are transferred, while in a polar covalent bond, electrons are shared

• In a nonpolar covalent bond, electrons are shared evenly, while in a polar covalent bond, electrons are shared unequally

• To reach the most stable energy state

What is the role of the valence shell in determining an atom's stability?

• It determines the atom's charge

• It determines the atom's stability
