Answer:
Blank 1 - 2
Blank 2 - 4
Blank 3 - 3
Explanation:
The unbalanced chemical equation given in the question is as follows:
Au2O3 → Au + O2
To balance a chemical equation, the number of atoms of each element on both sides of the equation (reactants and product) must be the same. Based on this explanation, the balanced chemical equation is as follows:
2Au2O3 → 4Au + 3O2
- 4 atoms of gold (Au) on both sides
- 6 atoms of oxygen on both sides
Hence, based on the question, blank 1, 2 and 3 are 2, 4 and 3 respectively.

I think you refer to Rutherford's Gold Foil Experiment alpha particles pass through because of the enormous amount of empty space inside the atom.
>>>more details here<<<
to have its trajectory affected the alpha particle has to pass "near" the nucleus to interact with the positive charge of the nucleus.
the fact is that internally the gold atoms are basically empty space and the nucleus represents only a small portion of the entire volume. only few alpha particles pass near the nucleus
