Is electricity positive electron

No. You are confusing general things here."Electricity" is a whole range of phenomena related to electrical charges.

An "electric current" involves the flow of charged particles - ANY charged particles, which may be positive or negative.

The most common case, for an electric current, is through the flow of electrons.

Electrons have a negative charge.

Positively charged electrons are actually anti-electrons, also known as positrons. For more details about this point, you may want to do some reading on "antimatter".
