How does an ionic bond form?
One atom gives an electron to another atom
Atoms share electrons
The electrons form a "sea of electrons"

The crystal in the image belongs to which crystal system?
Triclinic
Monoclinic
Hexagonal
Isometric
This crystal system has angles that all meet at 90°, but none of the axes are the same length: a≠b≠c and α=β=γ= 90°
Isometric
Triclinic
Hexagonal
Orthorhombic
This crystal system has angles that all meet at 90°, but one of the axes is not equal to the other 2: a=b≠c and α=β=γ= 90°
Hexagonal
Isometric
Tetragonal
Orthorhombic
In this crystal system, all of the axes are different lengths and two of the angles meet at 90°, one of them does not: a≠b≠c and α=γ= 90° β≠ 90°
Orthorhombic
Triclinic
