Draw isometric projection Spatial axes of the item are represented as similarly willing to the drawing floor and same distances alongside the axes are drawn the same.
<h3>What is isometric projection?</h3>
Definition of isometric projection an axonometric projection wherein the 3 spatial axes of the item are represented as similarly willing to the drawing floor and same distances alongside the axes are drawn same.
An isometric view of an item may be received via way of means of selecting the viewing path such that the angles among the projections of the x, y, and z axes are all of the same, or 120°. For example, with a cube, that is achieved via way of means of first searching immediately toward one face.

Answer : The crystal structure of Niobium is, BCC (Z=2)
Explanation :
Nearest neighbor distance, r =
Atomic mass of niobium (Nb) = 92.91 g/mole
Avogadro's number
First we have to calculate the cubing of edge length of unit cell for BCC and FCC crystal lattice.
For BCC lattice :
For FCC lattice :
Now we have to calculate the density of unit cell for BCC and FCC crystal lattice.
Formula used :
.............(1)
where,
= density
Z = number of atom in unit cell (for BCC = 2, for FCC = 4)
M = atomic mass
= Avogadro's number
a = edge length of unit cell
Now put all the values in above formula (1), we get
From this information we conclude that, the given density is approximately equal to the density of BCC unit lattice.
Therefore, the crystal structure of Niobium is, BCC (Z=2)
