IONIC COMPOUNDS

Question 1

What is an ion?

Answer 1

Ions are formed when atoms gain or lose electrons, they have a complete outer shell of electrons.

Question 2

Why do metals form positively charged ions?

Answer 2

Because metals loose electrons to have a full outer shell of electrons

Question 3

Why do ionic compounds conduct electricity when molten/aqueous?

Answer 3

Because the charged ions are free to move about and carry their charge.

Question 4

What are the melting/boiling point of ionic compounds

Answer 4

Ionic compounds have high melting/boiling point because ionic bonds are very strong and it requires a lot of energy to overcome them.

Question 5

What is the mass of an atom’s nucleus?

Answer 5

1/10000

Question 6

What are the boiling/melting points of ionic compounds like?

Answer 6

They have high melting/boiling points because ionic bonds are very strong and requires a lot of energy to overcome them
