23 symmetry elements are there in cubic system
It is a system of classification of crystals into 7 crystal systems(Cubic,Tetragonal,Othorgonal,Hexagonal,Trigonal.Monoclinic and Triclinic) on the basis of their Geometrical properties and symmetry (Diads,Triads,Tetrads,Planes of symmetry,Centre of symmetry)
Crystal systems are the way in which unit cells are categorized according to their axial and dimensional symmetry while crystal structure refers to size, shape, and atomic arrangement within the lattice.
Corundum is in the trigonal crystal system.
hexagonal crystal system ( 6 sided )
Mercury, at solidification temperatures, is classified in the trigonal crystal system.

you can determine crystal class and crystal system of a crystal from its symmetry by 3 criteria of symmetry.1.plane of symmetry:this divides the crystal into two such that one half of it is a mirror image to the other,e.g a halite(cube) has 9 plane of symmetry.(2)axis of symmetry:this is the axis about which the rotation takes place when a crystal wants to occupy position in space more than one time in a complete turn.(3).centre of symmetry:this when the like faces,edges e.t.c are arrange in pairs in corresponding position on the opposite side of the central point.

Corundum is in the trigonal crystal system.
hexagonal crystal system ( 6 sided )
Fluorite belongs to the same crystal system as salt - the cubic (also known as the isometric) crystal system.
Six crystal classes are known.
Atoms within a mineral are arranged into an orderly geometric spatial arrangement known as crystal structure. There are 14 basic crystal lattices (refered to as the Bravais lattices) which fit into one of 7 crystal system (triclinic, monoclinic, orthorhombic, tetragonal, rhombohedral, hexagonal and cubic) and all observed minerals fit into one crystal lattice and one crystal system. Diamond on the other hand is an allotrope of carbon arranged into an isometric hexoctahedral (Cubic-type) crystal system.
