Paper 2 · Atomic structure, metallic and ionic bonding, dot-and-cross diagram
Element D has an electron arrangement of 2,8,2 across its three shells, and exists as a solid metal. What type of bonding exists between particles of D in its elemental form?
AIonic bonding
BMetallic bonding
CCovalent bonding
DHydrogen bonding
Explanation: D is a metal (all its particles are the same element), so its particles are held together by metallic bonding -- a lattice of positive ions in a sea of delocalised electrons.
