What is electrostatic attraction?
an attractive force which 2 unlike charges exert on each other when they are kept a certain distance apart
an attractive force which 2 like charges exert on each other when they are kept a certain distance apart
an attractive force which 2 unlike charges exert on each other when they are pushed together
an attractive force which 4 unlike charges exert on each other when they are kept a certain distance apart
What is a structure with its particles arranged in a regular repeating pattern?
(a)
Why are crystal lattices fromed?
because like charge attract and opposite charges repel, the ions in an ionic compound stack up in a regular repeating pattern
because opposites attract and like charges repel, the ions in an covalent compound stack up in a regular repeating pattern
because opposites attract and like charges repel, the ions in an ionic compound stack up in a regular repeating pattern
because opposites attract and like charges repel, the ions in an metallic compound stack up in a unregulated repeating pattern
