I mean it depends what kind of halfway you’re talking about. The arithmetic mean of the masses of a Lithium atom and the Earth is 2.986x1027g.
(A Lithium atom’s mass is 1.153x10-23g according to google. The Earth’s is 5.972x1027kg.)
The geometric mean is a more likely calculation which is basically half way between them in terms of orders of magnitude. My calculator gives this at 262g, which is closer but certainly not the mass of a speck of dust.
