How can you identify the type of bonding based on the chemical formula?

• You look at the subscripts

• You look at the coefficient

• You can identify if the elements are metals and nonmetals

• You look at how many protons it has

Why are metals conductive?

• They are shiny

• The electrons are de-localised and able to move

• The electrons are held tightly within the lattice

What is the ability of a substance to be pulled into a thin strand?

• Malleability

• Conductivity

• Ductility

• Solubility

What type of bond is formed between metal ions when they share a "sea of electrons"?

• Covalent bond

• Ionic bond

• Metallic bond

• Hydrogen bond

Answer explanation

Metallic bond is formed between metal ions when they share a 'sea of electrons', allowing for the free movement of electrons throughout the structure.

In which of the following scenarios would you most likely find metallic bonding?

• Between two oxygen atoms

• In a piece of sodium chloride crystal

• In a pure gold ring

• In a water molecule

In this type of bond, electrons are delocalized in a "sea"

• Ionic

• Covalent

• Metallic

• Nonpolar

What is the primary characteristic of metallic bonding?

• Electrons are shared between atoms

• Electrons are transferred from one atom to another

• Electrons are delocalized and form a 'sea'

• Electrons are tightly bound to individual atoms

Which property of metals is directly related to metallic bonding?

• Brittleness

• High melting point

• Electrical conductivity

• Transparency

Why do metals tend to have high melting and boiling points?

• Due to strong covalent bonds

• Due to strong ionic bonds

• Due to strong metallic bonds

• Due to weak van der Waals forces
