Ionic Bonding

Question 1

Ions

Answer 1

Forms when atoms with low electronegativity (relative empty shells) bond with atoms with high electronegativity (relatively full shells) resulting in a transfer of electrons
Atoms lose electrons = positive charge
Atoms gain charge = negative charge

Question 2

Ionic bonding

Answer 2

Positive ions very strongly attracted to negative ions, but are repelled by each other
Results in a solid crystalline lattice of alternating positive and negative ions - strongly held in place but with moderately large spaces between them

Question 3

Ionic compounds

Answer 3

High melting and boiling points
Relatively low density
Hard but brittle
Poor thermal conductors
Electrical insulators in solid states
Good electrical conductors in molten or aqueous states
