Ionic Bonding

Question 1

Alkali metals

Answer 1

In group 1 e.g. lithium sodium potassium

Question 2

What are Bonds

Answer 2

These are forces of attraction that hold atoms together

Question 3

Why do atoms bond together and what do they need to achieve to do this

Answer 3

They bond together to come more stable. To do this they need to achieve Nobel gas configuration

Question 4

Ions

Answer 4

They are charged particles formed when an atom or groups of atoms gain or loose electrons

Question 5

What are cations

Answer 5

Metals loose electrons and form positive ions

Question 6

Anions

Answer 6

Non metals gain electrons and form negative ions

Question 7

Why do ionic compounds have high melting and boiling points

Answer 7

They have high melting points and boiling points because they have strong electrostatic forces between ions and requires a lot of energy to break

Question 8

Why are ionic compounds brittle

Answer 8

They are brittle because theres a repulsion

Question 9

When do ionic compounds conduct electricity and why

Answer 9

Ionic compounds only conduct electricity when molten(heated to a liquid state) or dissolved in a solution because they need to be free to carry charge

Question 10

Difference between ions and atoms

Answer 10

Atoms have the same number of protons and electrons but ions have an imbalance as they have an electrical charge
