The nature of ionic bonding

Question 1

What are the 3 types of strong chemical bonds?

Answer 1

ionic, covalent and metallic

Question 2

Why are noble gases very unreactive?

Answer 2

Because they have a full valence electron shell

Question 3

How many electrons do metals have in their valence shell?

Answer 3

1,2, or 3

Question 4

What is the easiest way for a metal to have a full outer shell?

Answer 4

To loose their valence electrons

Question 5

What is the easiest way for a non-metal to have a full outer shell?

Answer 5

To gain electrons because there are gaps in their outer shell

Question 6

What does ionic bonding occur between?

Answer 6

Metals and non-metals

Question 7

How are the electrons transferred during an ionic bond?

Answer 7

The metal transfers their electron(s) to the non-metal

Question 8

What type of charged ion does the non-metal become after gaining electrons from the metal?

Answer 8

A negatively charged ion

Question 9

What type of charged ion does the metal become after loosing an electron to the non-metal?

Answer 9

A positively charged ion

Question 10

Why and how is an attraction formed between the metal and the non-metal?

Answer 10

The metal looses its electrons to the non-metal, creating positively and negatively charged ions. These oppositely charged ions attract each other, creating a strong electrostatic force of attraction?

Question 11

What kind of attraction is made between the oppositely charged ions?

Answer 11

A strong electrostatic force of attraction

Question 12

What structure do ionic compounds exist as?

Answer 12

A lattice/giant ionic crystal

Question 13

How is a lattice/giant ionic crystal formed?

Answer 13

The strong electrostatic forces of attraction between the oppositely charged ions extends throughout the compound.

Question 14

Draw a diagram of the structure of a giant ionic crystal/lattice

Answer 14

Question 15

What state of matter are ionic compounds at room temperature?

Answer 15

Solid

Question 16

Why does a giant ionic crystal have a high boiling point?

Answer 16

Because there are strong electrostatic forces of attraction between the oppositely charged ions throughout the crystal which require a lot of energy to overcome/break.

Question 17

Do ionic compounds conduct electricity?

Answer 17

Yes, but only when molten or dissolved in water.

Question 18

Why is it that the ionic compound has to be molten or dissolved in water before it can conduct electricity?

Answer 18

It is because electricity is all about the movement of electrical charge and so the charged ions in the ionic compound must be able to move in the liquid state in order to carry this charge.

Question 19

Why are ionic compounds brittle and shatter easily?

Answer 19

This because the compound is composed of alternating positive and negative ions, and, if given a sharp blow the pattern could be disrupted and positive ions and negative ions would be opposite each other. This would cause them to repel and the compound to shatter.

Question 20

Draw a diagram to show how ionic compounds can shatter

Answer 20

Check pg 46
