Schrodinger and heisenberg developed an alternate theory about atomic nature that contradicted some of bohr's model of the atom. how do changes resulting from new technology and evidence affect the reputation of the atomic theory?

They don't affect the reputation of atomic theory at all.

Explanation:

Schrödinger and Heisenberg extended the model of the atom, as did Thompson, Rutherford, and Moseley before them.

Each model was based on the best available information at the time.

The availability of new information may require a new atomic model, but it doesn't destroy the reputation of older ones.

am i too late?

explanation:

considering the question as per the attachment

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.
