Chооse the best аnswer tо fill the blаnks of the following pаssage. Some answers may be used more than once, some may not be used:One of the earliest models of atomic structure was the so-called 1) _____________________ model of J.J. Thompson, which imagined the atom as composed of tiny electrons dispersed through a positively charged atomic substance. However, the gold-foil experiment of 2) ___________________ showed that atoms were mostly empty space, with a tiny fraction of this volume occupied by very dense nuclei. That ‘empty space’ is now understood as an 3) __________________, occupied by electrons spread out across a large volume relative to their mass and the size of the nucleus. This information came to be incorporated into the 4)_________________ model, which treated the atom like a tiny solar system, with a positively charged nucleus occupying the center, and electrons moving in orbits around the nucleus as planets orbit the sun. But not long after this model was conceived, Erwin Schrodinger applied wave mechanics to the problem, producing the 5)___________________ model we use even today.
