2 Bonding, Structure and Properties of matter

Question 1

Explain the bond

What is ionic bonding

Answer 1

Metal+Non metal it is the electrostatic attraction between a positive and negative ion. Forming a ionic lattice.

Question 2

Explain the bond

What is a metallic bond

Answer 2

Metal+Metal. Giant metallic structure with delocalised electrons allowing for a charge to pass through

Question 3

Explain it

What is a covalent bond

Answer 3

This is when two non metals share one or more electrons to gain a full outer shell. This allows for strong intermolecular forces

Question 4

What are intermolecular forces

Answer 4

They determine the boiling point and melting point they are quite weak and increase due to the size of the molecule.

Question 5

What happens to magnesium when it reacts with oxygen

Answer 5

Magnesium forms a 2+ ion whilst oxygen forms a 2- ion. Magnesium needs to lose 2 electrons to gain that positive charge whilst oxygen needs to gain 2 electrons to have a negative 2- charge. When they are charged, they become electrostatically attracted to one another. The transfer of electrons allows them to fully bond. This electrostatic attraction is strong.
