Amber, Electricity, Proto-Element

'Electricity' is derived from the Greek for 'amber', which, according to Thales, among others, possesses characteristics such as the power to shock.  However, he does not explain how such characteristics are grounded in Water, which he proposes is the proto-element.  Nor, do the other pre-Socratics seem to regard them as significant with respect to their choices of the proto-element.  In contrast, that electric charge has since been determined not only to constitute the structure of every element, but also to define their differences, suggests that Electricity might be that proto-element itself.
