ionic extra Flashcards
Metals lose electrons from their valence shell forming
positively charged cations
Non-metal atoms gain electrons forming
negatively charged anions
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
overall electrically neutral
What are bigger positive or negative ions
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
