How to Locate Antimony on Periodic Table

Periodic table is arranged by atomic number, variety of prolots in the nucleus which is very same as number of electrons. The atomic number increases from left to ideal. Periodic table starts at optimal left ( Atomic number 1) and also ends at bottom best (atomic number 118). Therefore you can straight look for atomic number 51 to find Antimony on routine table.

Anvarious other way to review regular table and also situate an aspect is by using group number (column) and also duration number (row). To locate Antimony on periodic table look for cross area of team 15 and also period 5 in the contemporary routine table.

Crystal Structure of Antimony

The solid state structure of Antimony is Simple Trigonal.

The Crystal structure can be explained 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 regards to its lattice parameters, which are the lengths of the cell edges Lattice Constants (a, b and also c)

a b c
430.7 430.7 1127.3 pm

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

alpha beta gamma
π/2 π/2 2 π/3

The positions of the atoms inside the unit cell are described by the collection of atomic positions ( xi, yi, zi) measured from a reference lattice suggest.

The symmetry properties of the crystal are described by the principle of space groups. All feasible symmetric arrangements of pwrite-ups in three-dimensional room are defined by the 230 space groups (219 distinct types, or 230 if chiral copies are thought about distinctive.
