Ionic compounds

Question 1

What are the three types of strong chemical bonds?

Answer 1

• ionic bonds
• covalent bonds
  -metallic bonds

Question 2

How are ions formed?

Answer 2

It is atoms that have gained or lost electrons, giving them an overall charge.

Question 3

What is the correct answer:
Ionic bonding involves a transfer of electrons from

a) metal to metal atoms
b)non-metal to metal atoms
c)metal to non-metal atoms

Answer 3

c

Question 4

How do ions transfer electrons?

Answer 4

Metal atoms lose electrons = positively charged ions.
The non-metal atoms gain electrons = negatively charged ions

Question 5

What is ionic bond?

Answer 5

It is a strong electrostatic force of attraction between the positive metal ion and the negative non-metal ion.

Question 6

Facts about ionic compounds:

Answer 6

-Have high melting and boiling points
-do not conduct electricity when solid, because the ions cannot move
-do conduct electricity when molten or in solution, because the charged ions are free to move about and carry their charge.
