ionic extra

Question 1

Metals lose electrons from their valence shell forming

Answer 1

positively charged cations

Question 2

Non-metal atoms gain electrons forming

Answer 2

negatively charged anions

Question 3

The ions form a lattice structure which is an evenly distributed crystalline structure
Ions in a lattice are arranged in a regular repeating pattern so that positive charges cancel out negative charges

The attraction between the cations and anions is occurring in all directions
Each ion is attracted to all of the oppositely charged ions around it

Therefore the final lattice is

Answer 3

overall electrically neutral

Question 4

What are bigger positive or negative ions

Answer 4

negative ions

As the formation of a negative ion increases the ionic radius and the formation of a positive ion decreases the ionic radius the negative ion will be larger than the positive ion
