WebAnswer (1 of 7): This property is called as variable valency. Some elements show variable valency because of the different electronic configurations. An atom of an element can sometimes lose more electrons than are present in its valence shell i.e. loss from the penultimate shell and hence exhibi... WebIt has a high melting point, but it is as light as aluminum. That means it has relatively low density, about 2.98g/cm 3. Its melting point is 1541 o C and boiling point is 2836 o C. Scandium chemical symbol is Sc. Its atomic … WebWhy can transition metals show variable valency? 4s electrons are lost before 3d. the presence of the 3d subshell raises the energy of the 4s electrons to above the 3d, therefore...
