The electron sea model explains following physical properties of metal :
Elelctrical conductance
Mealleability
Both a and b
reactivity with non metals
As we have learned
Electron sea model -
All atoms contribute to form a pool of electrons which is mobile.Leaving the valence electron, the remaining portion of the metal atom is a positive ion called Kernel.The positive ions or kernel are held in the three-dimensional space in a definite pattern in the sea of mobile electrons.
-
Electron sea model doesn't explain reactivity of metals with non metals .
It expalins the electrical conductance and mealleability
