Ionic bonds

Question 1

Define the term ionic bonding

Answer 1

The electrostatic attraction between oppositely charged ions.

Question 2

Explain why calcuim oxide has a high melting point:

Answer 2

Calcium oxide has a high melting point because it has a strong electrostatic attraction between particles and it requires lots of energy to overcome. Also, Calcium oxide is a ionic compound.

Question 3

State and explain why calcium oxide conducts electricity as a solid:

Answer 3

Calcium oxide will not conduct electricity as a solid as the electrostatic attraction stops ions from moving.

Question 4

What is oxidation?

Answer 4

Oxidation is the loss of electrons.

Question 5

What is reduction?

Answer 5

Reduction is the gain of electrons.

Question 6

How do you remember reduction and oxidation?

Answer 6

LEO GER ( Loss electrons Oxidation, Gain electrons reduction)

Question 7

WHat is the definition of an ion?

Answer 7

An ion is an atom or molecule with a net electrical charge due to loss or gain of electrons.

Question 8

What is the definition of electrostatic?

Answer 8

non-contact forces; they pull or push on objects without touching them.
