The fact that electrons occupy certain specified energy levels in which they are radiation less solves the problems associated with the Rutherford model.

<h3>What is the Bohr-Sommerfeld Model?</h3>

According to the Bohr-Sommerfeld Model of the atom, the electrons in an atom tend to occupy certain specified energy levels in which they are radiation less.

Recall that following from the Rutherford model and the and the Maxwell's laws, an accelerating charge radiates energy. Thus, the bottle neck is removed by assuming that electrons occupy specific energy levels in which they do not move about an loose energy.

This eliminates the possibility that the electron could spiral into the nucleus.

1. New technology is developed that provides more information about the theory.

2. New experimental methods are designed to test a theory.

3. A single experiment produces results that differ from all previous experiments.

Answer:

A secondary pollutant

Explanation:

Pollutants can broadly be classified into two main categories based on their formation or synthesis. 1: Primary pollutants, 2: Secondary pollutants.

1: Primary pollutants

Primary pollutant can be considered as any environmental pollutant that is being directly emitted from a certain source like when we burn coal carbon di oxide is directly emitted into the atmosphere so CO2 is a primary pollutant.

Similarly sulfur di oxide or SO2 is also a primary pollutant that is emitted by the gas emissions of motor vehicles.

2: Secondary pollutants:

On the other hand, secondary pollutant is something that is not directly emitted on earth as an environmental pollutant but some how it is formed due to a reaction of primary pollutant.

Such as mentioned in the question that SO2 when oxidized in air in the presence of enzymes and water, it form H2SO4 or acid rain which directly falls on earth and incurs great amount of damage to not only living organisms but also non-living organisms such as marble buildings.

Therefore, acid rain is secondary pollutant. Please see picture for better understanding.

Hope it help!
