The outermost valence electrons of each atom are negatively charged, so there is a negative Coulomb electrostatic repulsion between atoms, and they are separated from each other (floating), but this distance is very small, only 10-8 to 10-7 cm, so this floating can not be observed at all, nor can it be felt.

The+-sign in the figure represents the smallest inseparable unit of positive and negative electromagnetic information-quantum bit.

(john wheeler, a famous physicist, once famously said: Everything comes from bit by bit.

After the prosperity of quantum information research, this concept has been sublimated to everything from quantum bits.

Note: One point is one point.
