Chemistry- Bonding

Question 1

If the question doesn’t specify then the following states which type of bond the question is about.
(I) Ionic
(M) Metallic
(GC) Giant covalent
(SC) Simple covalent

Answer 1

Just say 5 once you’ve read it and don’t complain to me if you’re confused. I made these flashcards for me not you.

Question 2

What is bonded? (I)

Answer 2

Metals and non-metals

Question 3

What is formed when electrons are transferred? (I)

Answer 3

Ions

Question 4

Describe the structure of an ionic compound

Answer 4

• Giant lattice
• Oppositely charged ions
• Strong electrostatic forces of attraction

Question 5

Describe the mp/bp of ionic compounds and explain why

Answer 5

High mp/bp because strong bonds need lots of energy to break

Question 6

Can it conduct when solid? (I)

Answer 6

No because ions are fixed in place

Question 7

In which states do ionic compounds conduct electricity?

Answer 7

Aqueous and liquid

Question 8

Why does it conduct when liquid or aq? (I)

Answer 8

Ions are free to move and carry a charge through the substance

Question 9

What is bonded? (M)

Answer 9

Metals

Question 10

What happens to outer shell electrons when metals bond?

Answer 10

They are lost and become delocalised

Question 11

What is the structure? (M)

Answer 11

• Giant lattice
• Strong electrostatic forces of attraction
• Positive ions and a sea of electrons

Question 12

Describe the mp/bp of metallic compounds and explain why

Answer 12

High because of strong electrostatic forces of attraction

Question 13

Describe why metallic compounds can conduct electricity

Answer 13

Electrons are free to carry a charge through the substance

Question 14

Why are metallic compounds soft and malleable?

Answer 14

Ions are arranged in layers so can slide over each other

Question 15

What is bonded? (SC)

Answer 15

Two or more non-metals

Question 16

What happens to the electrons? (SC)

Answer 16

They’re shared between atoms so that both get a full outer shell

Question 17

Describe the structure of a simple covalent compound

Answer 17

• Small molecules
• Always with discrete number of atoms

Question 18

Describe the mp/bp of simple covalent and explain why

Answer 18

Low because of weak inter-molecular forces that are easily broken with heat

Question 19

Can it conduct? (SC)

Answer 19

Nope. There are no free electrons to carry a charge so nope.

Question 20

How many carbons are bonded to each other in diamonds? (GC)

Answer 20

4

Question 21

Describe the structure of a diamond

Answer 21

• Lattice with strong covalent bonds

Question 22
