ELEMENT COMPOUND & LATTICE

• A chemical element or element is a species of atoms having the same number of protons in their atomic nuclei.
• A compound is a molecule made of atoms from different elements. All compounds are molecules, but not all molecules are compounds.In mathematics,
• A lattice is one of the fundamental algebraic structures used in abstract algebra.
• 

ELEMENTS

• Elements can be one or more than one hundred substances that cannot be chemically interconverted or broken down into simpler substances and are primary constituents of matter. Each element is distinguished by its atomic number, i.e. the number of protons in the nuclei of its atoms.
• 

COMPOUNDS

• The ratio of each element is usually expressed by chemical formula. For example, water (H2O) is a compound consisting of two hydrogen atoms bonded to an oxygen atom. The atoms within a compound can be held together by a variety of interactions, ranging from covalent bonds to electrostatic forces in ionic bonds.
• 

LATTICES

• A structure consisting of strips of wood or metal crossed and fastened together with square or diamond-shaped spaces left between, used as a screen or fence or as a support for climbing plants,an interlaced structure or pattern resembling a lattice. or a regular repeated three-dimensional arrangement of atoms, ions, or molecules in a metal or other crystalline solid.or
