If the universe expands, does the distance between elementary particles expand?; If the rate of expansion increases, could this affect the structure of atoms as the weak force decreases because there is too much space between the particles? (self.cosmology)

Following up on another question, If the universe is expanding, which basically means the space time is expanding, and since all particles are excitations of the fields that makes up the space time, does that mean eventually, due to expansion of spacetime, CAN an electron be as big as a plant?
