Bivalves have strong muscles in order to hold their shells closed.
electrons need a closed loop called what in order to move?
An atom stripped of its valence electrons, so that its remaining electrons are all in closed shells.
When the shells are closed. If open, tap them and if they close then they are safe to eat. If they do not close then they are not edible.
