Properties of Transition Metals VS Calcium

28/02/2011· Melting Point Transition metals have high melting points due to their strong metallic bonding. Metallic bonding is defined by delocalization of valence electrons, leaving the metal ions to be eedded in a sea of delocalized electrons. More delocalized electrons, the stronger the metallic bonds. As seen in transition metals, not only some 3d electrons are…

GCSE Bonding

Most elemental metals have got metallic bonds, which in reality is a sea of electrons keeping metal ions together. This occurs due to the fact that metals would like to lose an electron, in order to have a noble gas configuration, and this is possible if an electron is free to jump from one atom to another.
