How to find Magnesium on routine Table
Periodic table is arranged by atom number, number of protons in the nucleus i beg your pardon is same as number of electrons. The atom number rises from left come right. Routine table beginning at top left ( atomic number 1) and ends at bottom right (atomic number 118). As such you can directly look for atomic number 12 to find Magnesium on periodic table.
Another way to read routine table and locate an element is through using team number (column) and duration number (row). To situate Magnesium on periodic table look because that cross ar of team 2 and period 3 in the modern periodic table.

Crystal structure of Magnesium
The hard state structure of Magnesium is Simple Hexagonal.
The crystal structure can be described in regards to its unit Cell. The unit cell repeats chin in three dimensional an are to form the structure.
Unit cell Parameters
The unit cabinet is stood for in terms of its lattice parameters, which are the lengths that the cabinet edges Lattice Constants (a, b and c)
| 320.94 | 320.94 | 521.08 pm |
and the angles in between them Lattice angle (alpha, beta and gamma).
| π/2 | π/2 | 2 π/3 |
The location of the atoms within the unit cell are described by the set of atom positions ( xi, yi, zi) measured indigenous a recommendation lattice point.
The symmetry properties of the crystal are explained by the ide of an are groups. All feasible symmetric species of particles in three-dimensional room are described by the 230 space groups (219 distinct types, or 230 if chiral duplicates are taken into consideration distinct.
