chemistry- diamond

Question 1

What type of bonding is present in diamonds?

Answer 1

• strong covalent bonding

Question 2

What type of atoms make up a diamond?

Answer 2

• carbon atoms

Question 3

What holds together the atoms in a diamond?

Answer 3

• strong covalent bonds

Question 4

Describe the relative hardness of a diamond

Answer 4

• Diamonds are very hard substances

Question 5

How many bonds does each carbon make in a diamond?

Answer 5

• 4 bonds

Question 6

Eplain the elctrical conductivity of a diamond.

Answer 6

• diamonds are not conductive as theres no presnece of a delocalised electron (a free electron) which can carry the charge

Question 7

Eplain the melting point of diamonds

Answer 7

diamonds have a very high melting and boiling point, as the network is held together by strong covalent bonds that need a lot of energy to break

Question 8

Similarity in strong covalent substances and in simple covalent substances

Answer 8

• both cannot conduct electricity

Question 9

Differences in strong covalent substances and in simple covalent substances

Answer 9

• Strong covalent have a higher melting and bioling point than the simple covalent

Question 10

Why is a diamond a hard substance?

Answer 10

• giant lattice arrangement

Question 11

Why does a diamond have a high mellting point

Answer 11

• bonds

Question 12

Why cant a diamond conduct electricity?

Answer 12

• Delocalised electron

Question 13

What occurs in covalent bonding?

Answer 13

• When 2 or more non metals share pairs of electrong to have a stable electronic configuaration

Question 14

What occurs in ionic bonding?

Answer 14

-ionic bonding occurs between metals and non metals and the metals consist in losing electronsnand nonmetals, gaining electrons.
