The heaviest element known to science is Managerium.
This element has no protons or electrons, but has a
nucleus composed of 1 neutron, 2 vice-neutrons, 5 junior
vice-neutrons, 25 assistant vice-neutrons, and 125 junior
assistant vice-neutrons all going round in circles.
Managerium has a half-life of three years, at which
time it does not decay but institutes a series of reviews
leading to reorganization.
Its molecules are held together by means of the exchange
of tiny particles known as morons.
