Where's all that sodium coming from seen as millions of km long straight tails on comets, planets and Moons?
And what's accelerating it faster than ions? The sodium is nearly straight and consists of neutral single sodium atoms, compared to the slightly bent plasma / ion tail and the significantly bent dust tail. Single sodium atoms it must be as for molecules the calculated force by the solar wind is insufficient.

Not a comet, not even a meteor. This is the planet Mercury and its 24 Mkm long sodium tail!
