Question

How did the uncertainty principle influence thinking about the arrangement of electrons in atoms?

Scientists realized that electrons have different energies depending on their location within an atom.

 

  

Scientists realized that electrons could not be located in defined orbits.

 

  

Scientists realized that electrons could move from one energy level to another.

 

  

Scientists realized that electrons did not continually lose energy.

 

​

Answer 1

Heisenberg's Uncertainty Principle states that there is inherent uncertainty in the act of measuring a variable of a particle. Commonly applied to the position and momentum of a particle, the principle states that the more precisely the position is known the more uncertain the momentum is and vice versa.

Answer 2

Answer:Scientists realized that electrons could not be located in defined orbits.

Step-by-step explanation:

According the Heisenberg's uncertainty principle, the momentum and position of a particle cannot be simultaneously measured with precision. This implies that the position of a particle (including the electron) cannot be accurately determined with precision. This became a failure of the Bohr's model which postulated that electrons are located in definite orbits. By combining the wave particle duality of Louis De Broglie and the the idea of Max Plank, Erwin Schrödinger arrived at the wave mechanical model of the atom in 1927.
