The photoelectric effect occurs when light shines on a metal. ... Light of any frequency will cause electrons to be emitted.
Detergents are amphipathic molecules that contain polar or charged hydrophilic groups (heads) at the end of long lipophilic hydrocarbon groups (tails) (Figure 1). They are also known as surfactants because they decrease the surface tension of water.
There are six bond pair electrons around the central atom in Sulfur Hexafluoride. In order to attain the structure of least possible energy the Fluoride atoms attain the angle of 90° with respect to each other. And the bond pair electrons after maximum repulsion attain a
Octahedral Shape as shown below,
