Ionic and Covalent Bonding

Question 1

ionic bonding

Answer 1

transferring of electrons to gain a full outer shell

Question 2

giant lattice (ionic)

Answer 2

held by electrostatic force of attraction between oppositely charged ions

Question 3

giant lattice properties

Answer 3

electrostatic forces of attraction acting in all directions, requires energy to break, high melting and boiling point
