Exploring Chemical Bonding

What is an ionic bond?

• An ionic bond is a type of chemical bond formed through the electrostatic attraction between oppositely charged ions.

• A bond formed by the sharing of electrons between atoms.

• A temporary attraction between neutral molecules.

• A bond that occurs only in metals.

How do ionic bonds form between atoms?

• Ionic bonds occur when atoms collide and fuse together.

• Ionic bonds are formed by the attraction of neutral atoms without any charge.

• Ionic bonds form through the transfer of electrons from one atom to another, creating charged ions that attract each other.

• Ionic bonds form through the sharing of electrons between atoms.

What is a covalent bond?

• A covalent bond is a type of ionic bond.

• A covalent bond is a weak attraction between molecules.

• A covalent bond involves the transfer of electrons between atoms.

• A covalent bond is a chemical bond formed by the sharing of electron pairs between atoms.

Provide an example of a molecule with both ionic and covalent bonds.

• Ammonium sulfate (NH4)2SO4

• Glucose (C6H12O6)

• Sodium chloride (NaCl)

• Calcium carbonate (CaCO3)

What role do valence electrons play in bonding?

• Valence electrons are responsible for forming chemical bonds by being shared or transferred between atoms.

• Valence electrons are responsible for the color of substances.

• Valence electrons only exist in noble gases.

• Valence electrons are irrelevant in chemical reactions.

What is the difference between ionic and covalent bonds?

• Ionic bonds involve the transfer of electrons, while covalent bonds involve the sharing of electrons.

• There is no difference; they are the same type of bond.

• Ionic bonds are stronger than covalent bonds in all cases.

• Covalent bonds only occur in metals, while ionic bonds occur in nonmetals.

Which of the following compounds contains only ionic bonds?

• Water (H2O)

• Hydrogen chloride (HCl)

• Magnesium oxide (MgO)

• Carbon dioxide (CO2)
