Question

Crystal structure refers to the arrangement of protons, neutrons and electrons in an atom? True of false?

Answer 1

Ans. This statement is false because crystal structure refers to the arrangement of atoms, molecules or ions not the arrangement of proton, neutrons and electrons. As the proton, neutrons and electrons are very small particles then atoms. For crystal structure, mainly arrangement of atoms are reffered.

Different possibilities of atoms to form different crystal structure and these are

(1) Cubic close structre (2) trigonal crystal structure (3) tetragonal crystal structure (4) Hexagonal crystal structre (5) monoclinic crystal structure (6) Triclinic crystal structure (7) orthorhombic crystal structure
