Comparing metallic bonding and ionic bonding

Question 1

Distinguish

• Distinguish between metallic bonding, ionic bonding and covalent bonding

Answer 1

Ionic bonds are formed when two atoms exchange electrons to create a positive and negative ion. Covalent bonds are formed when atoms share electrons to create a molecule. Metallic bonds are created when metal atoms lose their outermost electron to form positively charged ions. Metallic bonding is the electrostatic attraction between positive metal ions and delocalised electrons.

Metallic bonding

Question 4

Define lattice

• Define lattice

Answer 4

he crystal lattice is the symmetrical three-dimensional structural arrangements of atoms, ions or molecules (constituent particle) inside a crystalline solid as points.

Question 5

Explain

• Explain the properties of metals and ionic substances, linking properties to bonding and structure

Answer 5

The properties of ionic compounds include forming crystal lattice structures, having high melting and boiling points, being hard and brittle and conducting electricity well when dissolved in water, but being insulators when in the solid form. The lattice energy is the energy of the bonds when in its crystal shape.The bonding that occurs in a metal is responsible for its distinctive properties: luster, malleability, ductility, and excellent conductivity.
