a Because aluminium has less than one-third the density of copper, an aluminium conductor of equivalent current carrying capacity is only half the mass of a copper conductor. With a significantly lower price per kilogram, aluminium is much more cost effective in many electrical applications. Symmetric ECs have specific energy values up to ~6 Wh/kg and higher power performance than asymmetric capacitors where designs having specific energy values approach 20 Wh/kg. There are other differences in the characteristics and performance of these two types leading to use in different applications. In the first place it is hard to see why the compounds of very high dielectric constant should be chiefly hydrogen compounds. Also hydrogen chloride should contain dipoles of greater moment than water or hydrogen fluoride, yet it has a much lower dielectric constant both in the vapor and liquid.

Kohler shower baseSodium, magnesium and aluminium. Sodium, magnesium and aluminium are all metals. They have metallic bonding, in which the nuclei of metal atoms are attracted to delocalised electrons. Going from sodium to aluminium: the charge on the nuclei increases … the number of delocalised electrons increases … With aluminium you have two s electrons and a p electron. When you remove said p electron then aluminium still at least has a full s orbital. That's why the first ionization energy is lower for Al. However the situation changes when you remove the second electrons from each.

Built 47re transmissionFirst electron in both cases has to be removed from 3s-orbital but the nuclear charge of Na (+ 11) is lower than that of Mg (+ 12) therefore first ionization energy of sodium is lower than that of magnesium.
