Ionic Bonding

Question 1

Ionic Bond

Answer 1

Electrostatic attraction between oppositely charged ions

Question 2

Ions

Answer 2

Formed when one or more electrons are transferred from one atom to another

Question 3

Sulfate ion

Answer 3

SO4 2-

Question 4

Hydroxide ion

Answer 4

OH -

Question 5

Nitrate ion

Answer 5

NO3 -

Question 6

Carbonate ion

Answer 6

CO3 2-

Question 7

Ammonium ion

Answer 7

NH4 +

Question 8

Giant Ionic compounds

Answer 8

Ionic crystals are giant lattices (regular structures) of ions
Giant = same basic unit repeated

Question 9

Conductive properties of ionic compounds

Answer 9

ONLY conduct electricity when molten/dissolved as ions are free to move and carry charge

Question 10

Melting points of ionic compounds

Answer 10

High melting point as giant ionic lattices are held together by strong electrostatic forces which require lots of energy to overcome

Question 11

Dissolving properties of ionic compounds

Answer 11

polar water molecules pull ions away from the lattice causing it to dissolve
