How to locate Rubidium on periodic Table
Periodic table is i ordered it by atom number, number of protons in the nucleus which is very same as number of electrons. The atomic number increases from left come right. Periodic table starts at height left ( atomic number 1) and also ends at bottom appropriate (atomic number 118). As such you can straight look for atomic number 37 to uncover Rubidium on routine table.
Another method to read periodic table and locate an aspect is by using team number (column) and period number (row). To situate Rubidium on periodic table look for cross section of group 1 and period 5 in the contemporary periodic table.

Crystal framework of Rubidium
The hard state framework of Rubidium is Body centered Cubic.
The decision structure deserve to be defined in regards to its unit Cell. The unit cells repeats itself in three dimensional room to kind the structure.
Unit cell Parameters
The unit cell is represented in regards to its lattice parameters, which space the lengths the the cabinet edges Lattice Constants (a, b and c)
| 558.5 | 558.5 | 558.5 pm |
and the angles between them Lattice angles (alpha, beta and also gamma).
| π/2 | π/2 | π/2 |
The location of the atoms within the unit cabinet are explained by the set of atomic positions ( xi, yi, zi) measured indigenous a recommendation lattice point.
The symmetry nature of the crystal are explained by the principle of an are groups. All possible symmetric kinds of particles in three-dimensional an are are explained by the 230 room groups (219 unique types, or 230 if chiral duplicates are taken into consideration distinct.
