Learning Objectives

2.7 Metallic bonding

Core	Supplement
	$1 Describe metallic bonding as the electrostatic attraction between the positive ions in a giant metallic lattice and a ‘sea’ of delocalised electrons$
	$2 Explain in terms of structure and bonding the properties of metals: (a) good electrical conductivity (b) malleability and ductility$
