Arrange the chemical elements silicon sodium aluminum in order to enhance the metallic properties.

In this case, it should be taken into account that the metallic properties increase with an increase in the probability of electron detachment from the external electronic level. And this primarily depends on the removal of this electronic level from the nucleus of a given atom. and with an increase in the number of electrons at the outer electronic level, the radius at which the valence electrons are located shrinks or decreases. So, based on this, we get that the metallic properties increase in the next row of chemical elements. Namely.
Silicon, aluminum, sodium.
