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 97 to find Berkelium 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 Berkelium on periodic table look for cross section of group N/A and period 7 in the modern periodic table.

The element Berkelium was discovered by Lawrence Berkeley National Laboratory in year 1949 in United States . Berkelium derived its name from Berkeley, California, where the element was first synthesized, by analogy with terbium
The table below shows the abundance of Berkelium in Universe, Sun, Meteorites, Earth's Crust, Oceans and Human Body.
The solid state structure of Berkelium 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.
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)
and the angles between them Lattice Angles (alpha, beta and gamma).
The positions of the atoms inside the unit cell are described by the set of atomic positions ( xi, yi, zi) 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.
Berkelium atoms have 97 electrons and the electronic shell structure is [2, 8, 18, 32, 27, 8, 2] with Atomic Term Symbol (Quantum Numbers) 6H15/2.
Shell Structure of Berkelium - Electrons per energy level
The ground state electronic configuration of Neutral Berkelium atom is [Rn] 5f9 7s2. The portion of Berkelium configuration that is equivalent to the noble gas of the preceding period, is abbreviated as [Rn]. For atoms with many electrons, this notation can become lengthy and so an abbreviated notation is used.This is important as it is the Valence electrons 5f9 7s2, electrons in the outermost shell that determine the chemical properties of the element.
