Vanliga molekyler

A molecule may be homonuclear, that is, it consists of atoms of one chemical element, e.g. two atoms in the oxygen molecule (O 2); or it may be heteronuclear, a chemical compound composed of more than one element, e.g. water (two hydrogen atoms and one oxygen atom; H 2 O).

Vad är en molekyl enkel förklaring

Molecule, a group of two or more atoms that form the smallest identifiable unit into which a pure substance can be divided and still retain the composition and chemical properties of that substance. Learn more about the properties and structures of molecules in this article.

    1. Vad är en atom enkel förklaring

    The atom is the basic particle of the chemical elements, and the chemical elements are distinguished from each other by the number of protons that are in their atoms. For example, any atom that contains 11 protons is sodium, and any atom that contains 29 protons is copper. The number of neutrons defines the isotope of the element.

    Bindingar og formlar. Alle molekyl har eit namn og ein kjemisk formel, som fortel kva atom dei består av, og kor mange det er av kvart atom i molekylet. CO 2 er den kjemiske formelen for karbondioksid. C står for eitt karbonatom, og O 2 fortel at det er to oksygenatom i molekylet.

      In \(\ce{NH_3}\), nitrogen atom \(\ce{N}\) has 3 different single covalent bonds with 3 different hydrogen atoms. Therefore it's a molecule as well. In \(\ce{NaF}\), sodium atom \(\ce{Na}\) has an ionic bond with fluorine atom \((\ce{Na-F}).\) Therefore it's not a molecule.
