108 Hs - Hassium | SchoolMyKids

Hassium is a chemical element with symbol Hs and atomic number 108, named after the German state of Hesse. It is a synthetic element (an element that can be created in a laboratory but is not found in nature) and radioactive; the most stable known isotope, 269Hs, has a half-life of approximately 9.7 seconds, although an unconfirmed metastable state, 277mHs, may have a longer half-life of about 130 seconds. More than 100 atoms of hassium have been synthesized to date.

How to Locate Hassium 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 108 to find Hassium 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 Hassium on periodic table look for cross section of group 8 and period 7 in the modern periodic table.

Crystal Structure of Hassium

The solid state structure of Hassium is Simple Hexagonal.

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)

a b c

and the angles between them Lattice Angles (alpha, beta and gamma).

alpha beta 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 Hassium - neutral Hassium atom

The ground state electronic configuration of Neutral Hassium atom is [Rn] 5f14 6d6 7s2. The portion of Hassium 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 6d6 7s2, electrons in the outermost shell that determine the chemical properties of the element.
