Californium is a radioactive metallic chemical element with symbol Cf and atomic number 98. The element was first made in 1950 at the University of California Radiation Laboratory in Berkeley, by bombarding curium with alpha particles (helium-4 ions). It is an actinide element, the sixth transuranium element to be synthesized, and has the second-highest atomic mass of all the elements that have been produced in amounts large enough to see with the unaided eye (after einsteinium).

Periodic table is arranged by atomic number, number of protons in the nucleus which is same as number of
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
98 to find Californium 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 Californium on periodic
table look for cross section of group N/A and period
7 in the modern periodic table.

The element Californium was discovered by Lawrence Berkeley National Laboratory in year
1950 in United States
derived its name from California, where the element was first synthesized
The table below shows the abundance of Californium in Universe, Sun, Meteorites,
Earth's Crust, Oceans and Human Body.
The solid state structure of Californium is Simple Hexagonal.
The Crystal structure can be described in terms of its unit Cell. The unit Cells repeats itself in
dimensional space to form the structure.
The unit cell is represented in terms of its lattice parameters, which are the lengths of the cell
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.
Californium atoms have 98 electrons and
the electronic shell structure is [2, 8, 18, 32, 28, 8, 2] with Atomic Term Symbol (Quantum Numbers) 5I8.
Shell Structure of Californium - Electrons per energy
The ground state electronic configuration of Neutral Californium atom is
[Rn] 5f10 7s2.
The portion of Californium 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 5f10 7s2, electrons in
the outermost shell that determine the chemical properties of the element.
