How to Locate Neon 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 10 to find Neon 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 Neon on periodic table look for cross section of group 18 and period 2 in the modern periodic table.
The element Neon was discovered by W. Ramsay and W. Travers in year 1898 in United Kingdom. Neon was first isolated by W. Ramsay and W. Travers in 1898. Neon derived its name from the Greek neos, meaning 'new'.
In June 1898 Ramsay separated a new noble gas from liquid argon by difference in boiling point.

Crystal Structure of Neon
The solid state structure of Neon is Face Centered Cubic.
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)
|442.9 pm||442.9 pm||442.9 pm|
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.

Ground State Electronic Configuration of Neon - neutral Neon atom
Abbreviated electronic configuration of Neon
The ground state abbreviated electronic configuration of Neutral Neon atom is [He] 2s2 2p6. The portion of Neon configuration that is equivalent to the noble gas of the preceding period, is abbreviated as [He]. 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 2s2 2p6, electrons in the outermost shell that determine the chemical properties of the element.
