How to Locate Tennessine 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 117 to find Tennessine 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 Tennessine on periodic table look for cross section of group 17 and period 7 in the modern periodic table.
The element Tennessine was discovered by Yuri Oganessian et al.(JINR in Dubna) in year 2010 . Tennessine was first isolated by in . Tennessine derived its name from Tennessee, United States.

Crystal Structure of Tennessine
The solid state structure of Tennessine is .
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)
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 Tennessine - neutral Tennessine atom
Abbreviated electronic configuration of Tennessine
The ground state abbreviated electronic configuration of Neutral Tennessine atom is [Rn] 5f14 6d10 7s2 7p5. The portion of Tennessine 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 7s2 7p5, electrons in the outermost shell that determine the chemical properties of the element.
