How to situate Magnesium on periodic Table
Periodic table is arranged by atomic number, number of protons in the nucleus i m sorry is exact same as number of electrons. The atomic number increases from left come right. Routine table start at height left ( atom number 1) and ends at bottom ideal (atomic number 118). Thus you can directly look because that atomic number 12 to uncover Magnesium on routine table.
Another means to read regular table and locate an aspect is by using group number (column) and period number (row). To locate Magnesium on periodic table look because that cross ar of group 2 and period 3 in the modern-day periodic table.

Crystal structure of Magnesium
The hard state structure of Magnesium is Simple Hexagonal.
The crystal structure deserve to be described in terms of its unit Cell. The unit cells repeats itself in three dimensional an are to kind the structure.
Unit cabinet Parameters
The unit cell is represented in terms of its lattice parameters, which room the lengths of the cell edges Lattice Constants (a, b and also c)
and the angles in between them Lattice angles (alpha, beta and also gamma).
The positions of the atoms within the unit cell are explained by the collection of atom positions ( xi, yi, zi) measured indigenous a referral lattice point.
The symmetry properties of the decision are described by the principle of an are groups. All possible symmetric species of corpuscle in three-dimensional an are are defined by the 230 an are groups (219 unique types, or 230 if chiral copies are taken into consideration distinct.
