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 110 to find Darmstadtium 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 Darmstadtium on periodic table look for cross section of group 10 and period 7 in the modern periodic table.
The element Darmstadtium was discovered by Gesellschaft für Schwerionenforschung in year 1994 in Germany . Darmstadtium derived its name from Darmstadt, Germany, where the element was first synthesized

The solid state structure of Darmstadtium is Body 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.
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.

Shell Structure of Darmstadtium - Electrons per energy level
The ground state electronic configuration of Neutral Darmstadtium atom is [Rn] 5f14 6d9 7s1. The portion of Darmstadtium 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 5f14 6d9 7s1, electrons in the outermost shell that determine the chemical properties of the element.
