Question

select the correct answer.
which statement about schrödingers theory of the atomic model is true?
a. it proved that the nucleus of an atom is positively charged.
b. it was the first theory to discuss the existence of electrons.
c. it explained the odds of finding the position of an electron.
d. it assumed the electron cloud to be heavier than the nucleus.

Explanation:

• Option A: Rutherford's gold foil experiment proved the positively charged nucleus, not Schrödinger's theory.
• Option B: The existence of electrons was first discussed in J.J. Thomson's plum pudding model, predating Schrödinger's work.
• Option C: Schrödinger's quantum mechanical model uses wave functions to describe the probability (odds) of finding an electron in a specific region of space.
• Option D: The nucleus contains nearly all of an atom's mass, so the electron cloud is far lighter than the nucleus, making this statement false.

Answer:

C. It explained the odds of finding the position of an electron.
