Major Ideas: Review Of Strong Bonding

Question 0

What happens when you increase the positive ions in the metallic lattice?

Answer 0

The attraction between the positive ions and delocalised electrons also increase

Question 1

What is metallic bonding?

Answer 1

Electrostatic attraction of positive metal ions and delocalised electrons

Question 2

What happens when the atomic radii of metal atoms INCREASE down the group?

Answer 2

Attraction of positive ions for delocalised electrons DECREASES

Question 3

How do metals behave in reactions when they lose electrons?

Answer 3

Reductants

Question 4

What is ionic bonding?

Answer 4

The electrostatic attraction between positive ions and negative ions in a crystal lattice

Question 5

In the formation of ionic compounds, what so metals (with lower ionisation energies) and non-metals form?

Answer 5

Metals: cations/positive ions

Non metals: anions/ negative ions

Question 6

What is covalent bonding?

Answer 6

Results from the electrostatic attraction between atomic nuclei and shared electrons occupying the region of space between these nuclei

Question 7

What if covalent MOLECULAR bonds?

Answer 7

Covalent bonds WITHIN the molecule are strong, but the bonding BETWEEN molecules are weak

Question 8

What is covalent NETWORK bonds?

Answer 8

Strong bonding extends throughout entire lattice
