How to Locate Copernicium on Periodic Table

Periodic table is arranged by atomic number, number of protons in the nucleus which is same as number of electrons. The atomic number increases from left to right. Periodic table starts at top left ( Atomic number 1) and ends at bottom right (atomic number 118). Therefore you can directly look for atomic number 112 to find Copernicium on periodic table.

Another way to read periodic table and locate an element is by using group number (column) and period number (row). To locate Copernicium on periodic table look for cross section of group 12 and period 7 in the modern periodic table.

Crystal Structure of Copernicium

The solid state structure of Copernicium is Simple Hexagonal.

The Crystal structure can be described in terms of its unit Cell. The unit Cells repeats itself in three dimensional space to form the structure.

Unit Cell Parameters

The unit cell is represented in terms of its lattice parameters, which are the lengths of the cell edges Lattice Constants (a, b and c)

a	b	c
N/A

and the angles between them Lattice Angles (alpha, beta and gamma).

alpha	beta	gamma
N/A

The positions of the atoms inside the unit cell are described by the set of atomic positions ( x_i, y_i, z_i) measured from a reference lattice point.

The symmetry properties of the crystal are described by the concept of space groups. All possible symmetric arrangements of particles in three-dimensional space are described by the 230 space groups (219 distinct types, or 230 if chiral copies are considered distinct.
