Question

Question 14 Which statement is false? nThe probability of finding an electron at a given point in space is equal to the square of the amplitude of the electron wave. The electron density in an orbital ends abruptly at some imaginary circumference enclosing 90% of the electron density The p orbitals have the electron density equally distributed in two regions on opposite sides of the nucleus 4) All s orbitals are spherical in shape 5 With the 2s orbital, there are certain places where the electron density drops to zero.

Explanation / Answer

2 the electron density in orbital end abruptly at some imiginary circumference enclosing 90 percent electron density

Orbitals are generally drawn as three-dimensional surfaces that enclose 90% of the electron density, as was shown for the hydrogen 1s, 2s, and 3s orbitals in part (b) in Figure 1.2.2. Although such drawings show the relative sizes of the orbitals, they do not normally show the spherical nodes in the 2s and 3s orbitals because the spherical nodes lie inside the 90% surface
