Krypton (from Greek:κρυπτός kryptos "the hidden one") is a chemical element with symbol Kr and atomic number 36. It is a member of group 18 (noble gases) elements. A colorless, odorless, tasteless noble gas, krypton occurs in trace amounts in the atmosphere, is isolated by fractionally distilling liquefied air, and is often used with other rare gases in fluorescent lamps.

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
36 to find Krypton 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 Krypton on periodic
table look for cross section of group 18 and period
4 in the modern periodic table.

The element Krypton was discovered by William Ramsay in year
1898 in United Kingdom
derived its name from the Greek kryptos, meaning 'hidden'
The table below shows the abundance of Krypton in Universe, Sun, Meteorites,
Earth's Crust, Oceans and Human Body.
The solid state structure of Krypton is Face Centered Cubic.
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.
Krypton atoms have 36 electrons and
the electronic shell structure is [2, 8, 18, 8] with Atomic Term Symbol (Quantum Numbers) 1S0.
Shell Structure of Krypton - Electrons per energy
The ground state electronic configuration of Neutral Krypton atom is
[Ar] 3d10 4s2 4p6.
The portion of Krypton configuration that is equivalent to the noble gas of
the preceding period, is abbreviated as [Ar]. 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 3d10 4s2 4p6, electrons in
the outermost shell that determine the chemical properties of the element.
