a) Describe the nature of ionic bonding. b) State the electron configuration of the Ca (II) ion. c) Outlie why solid calcium is a good conductor of electricity.
a) Ionic bonding is the electrostatic attraction between oppositely charged ions (+ and -). [1]b) 1s22s22p63s23p6 [1]c) Metallic bonding occurs through delocalized electrons in solid calcium. Those electrons are the ones that can conduct electricity while they are mobile/free to move. [1]
