SORRY, YOU WERE INCORRECT.

HERE IS THE EXPLANATION OF THE QUESTION

 

 

#10. According to the quantum theory, point A in the above figure represents___________.

a. the fixed position of an electron - Electrons are in constant motion about the nucleus of an atom.

b. the farthest point from the nucleus that an electron can achieve - An electrons position can not be determined exactly, you can only determine the highest probability of where it will be located. Also an electron at point A could be excited to a higher energy level.

c. a position where an electron cannot exist - We know, from Bohr, that electrons can exist in regions called orbitals. Point A is on one of these orbitals.

d. a position where an electron probably exists - this is a very likely position for an electron, as it is near an orbital.
