A molecule possess an n-fold alternating axis of symmetry if,when rotated through an angle of 3600/n about this axis and then followed by reflection of in plane perpendicular to the axis;the molecule is indistinguishable from the original molecule.

In chemistry, the alternating axis of symmetry refers to a type of symmetry found in molecules with multiple C2 axes of symmetry that are perpendicular to one another. This type of symmetry results in a pattern in which the symmetry elements alternate along the molecule, creating a unique arrangement. Examples of molecules with alternating axis of symmetry include benzene and cyclohexane.
Point group D_n is a type of symmetry group in chemistry and crystallography. It has a 2-fold rotational axis with n total symmetry elements, including reflections and rotations. The "D" indicates that there are perpendicular C2 axes in the group.
A sea urchin has radial symmetry, meaning it is symmetrical around a central axis, like a wheel. This symmetry allows them to have multiple planes of symmetry passing through the central axis, giving them equal parts around the center.
Symmetry is a balance or harmonious arrangement of parts on either side of an axis or plane. Plane symmetry refers to symmetry in a two-dimensional plane where an object can be reflected across a line to produce an identical shape. This concept is commonly seen in objects like snowflakes or geometric figures.
Diatoms have radial symmetry, meaning they are symmetrical around a central axis or point.
A radial symmetry type repeats around the center of the organism, with body parts arranged around a central axis, like in jellyfish or sea anemones.
