The difference between cesium metal being soft and tungsten metal being hard has to be explained using electron-sea model. Concept introduction: Electron-sea model: Metals with single valence electron cannot not be localized because of less valence electrons to form electron pair. As a result valence electrons does not form electron pair bond between any atoms. But the valence electrons are delocalized and contributes for whole crystal. In electron sea model, metal cations are in a sea of electrons which moves freely in entire crystal. Figure 1 The delocalized electrons are responsible for electrostatic attraction between metal cation which held together.
