    The document compares and contrasts the seven crystal systems and three Bravais lattices of the cubic crystal system. The seven crystal systems are cubic, hexagonal, tetragonal, trigonal, orthorhombic, monoclinic, and triclinic. Each system has different characteristics based on the number and orientation of crystallographic axes. The three Bravais lattices of the cubic system are simple cubic, face-centered cubic, and body-centered cubic, which differ in their atomic arrangements.

    Let’s Check
    Let’s Analyze

    Activity 1. Compare and contrast the 7-crystal system.

    At least seven different crystal systems are used to categorize crystals based on their atomic
    configurations or lattices. The seven-crystal system's comparison and contrast structures are
    shown below:

    Cubic System

    - It is the intersection of all three axes at right angles and equal lengths. It also goes by
    the name "isometric system." Diamond-shaped cubes, octahedrons, rhombic
    dodecahedrons, and other shapes can be found in crystals.

    Hexagonal System

    - This system has four crystallographic axes, three of which are equal, or equilateral,
    horizontal axes that are located at 120 degrees from one another, and one of which is
    vertical and perpendicular to the other three. Compared to the horizontal axes, this
    vertical axis might be either longer or shorter. Arsenic, quartz, (the infamous) dolomite,
    emerald, ruby, and many other substances are examples of this.

    Tetragonal System

    - It consists of two axes that share the same plane and are equally long. Both long and
    short main axes can be present, and all three of them meet at right angles. Pyramids and
    four-sided prisms are a few examples of them

    Trigonal System

    - Also known as the rhombohedral system, it resembles the hexagonal system in terms
    of its axes and angles. The trigonal crystal's cross-section consists of three sides. Agate,
    amethyst, calcite, and other crystals are examples of trigonal crystals.

    Orthorhombic system

    - Three axes that are all of different lengths and at right angles to one another make up
    this crystal system. Topaz and tanzanite are only a few examples.

    Monoclinic System
    - Additionally, this includes three axes with various lengths. Two of them are at an angle
    to one another, while the third is slanted. Primitive and base-centered monoclinic cells
    are the two possible forms of monoclinic systems. Moonstone, serpentine, epidote, and
    other examples.

    Triclinic System

    - This crystal system's three axes likewise have three axes with varying lengths and a
    stronger tendency to point in the same direction. Rhodonite and turquoise are a few
    examples.

    Activity 2. Compare and contrast the 3 Bravais lattice of the cubic crystal system.

    - The body-centered cubic lattice and the face-centered cubic lattice are both non-
    primitive since they comprise more than one lattice. The three Bravais Lattice of the
    cubic crystal system has a cubic symmetry that distinguishes the simple or primitive
    cubic.

    In a Nutshell

    a.) Simple Cubic


    b.) Face-centered Cubic
    c.) Body-Centered Cubic
    d.) Hexagonal Crystal System
