Which of the following is NOT a characteristic of metallic bonding?

• It involves the sharing of free electrons among a lattice of metal atoms.

• It occurs only between non-metal atoms.

• It allows metals to conduct electricity.

• It gives metals their malleability and ductility.

• Ionic bond

• Covalent bond

• Metallic bond

• Hydrogen bond

What is a hydrogen bond?

• A strong bond that holds hydrogen atoms together

• A type of ionic bond involving hydrogen

• A weak bond between two molecules resulting from an electrostatic attraction

• A covalent bond that only occurs in hydrogen atoms

Which statement best describes an ionic bond?

• It forms between atoms that share electron pairs equally.

• It forms between atoms that share a metallic lattice.

• It forms between atoms when one atom gives up an electron to another atom.

• It forms only between molecules of water.

Why do atoms form bonds?

• To increase their energy levels

• To decrease their stability

• To fulfill the octet rule and achieve stability

• To become isotopes

What is the octet rule?

• Atoms seek to have eight electrons in their outer electron shell.

• Atoms prefer to have no more than eight protons.

• Atoms aim to transfer exactly eight electrons when bonding.

• Atoms must have eight neutrons to be stable.
