19) According to the Heisenberg Uncertainty Principle A) an electron can never appear in the exact same position twice. B) electrons must always absorb energy when moving to higher quantum levels. C) s orbitals are spherical in nature. D) you cannot accurately know both the position and momentum of an electron at the same time.

Answer :

Answer:D

Explanation:

Heisenberg’s uncertainty principle in quantum physics by German physicist Werner Heisenberg in 1927 states that the more accurately the velocity of an object (electron) is determined , the less accurate the position of the object is known and vice versa. The principle talks about how difficult it is to determine the precision of two related parameters.

Answer: The correct option is D (you cannot accurately know both the position and momentum of an electron at the same time.)

Explanation:

Werner Heisenberg in 1927 introduced the uncertainty principle in quantum physics which stated that the more precisely the position is known the more uncertain the momentum is and vice versa. Meaning that you cannot accurately know both the position and momentum of an electron at the same time. For example you can not effectively determine the velocity of an object in motion and it's position the same time.
