The correct answer is A, electrons enter orbitals of lowest energy first. The Aufbau principle states that electrons orbiting atoms fill the lowest energy levels available before filling higher levels. Following this, molecules can go into the most stable electron configuration.
Answer:


Explanation:
a)At the base of the surface the Electric flux is easy to find, because the Electric Field is constant in magnitude and perpendicular to the flat surface:

The Flux is negative because the Electric field goes into the surface
b) The Gaussian surface in form of a hemisphere encloses no net charge. The Gauss law says that the Flux of the electric field is proportional to the net charge enclosed. At this case, the charge is zero, then the total Flux is zero too.

Then:

The Flux is positif because the Electric field goes out of the surface.
