molecule
In chemistry and physics, the smallest particle of a substance that consists of two or more atoms held together by chemical bonds.
Ein Wassermolekül besteht aus zwei Wasserstoffatomen und einem Sauerstoffatom.
A water molecule consists of two hydrogen atoms and one oxygen atom.
'Molekül' (molecule) is a technical term from the natural sciences, especially chemistry and physics. Even though the word is generally known, it is mainly used in scientific or educated-language contexts.
Im Chemieunterricht lernen wir den Aufbau von Molekülen.
In chemistry class, we learn about the structure of molecules.
To describe the composition of a molecule, you often use the construction 'besteht aus' (consists of) + dative. A molecule always consists of several atoms.
Ein Zuckermolekül besteht aus Kohlenstoff-, Wasserstoff- und Sauerstoffatomen.
A sugar molecule consists of carbon, hydrogen, and oxygen atoms.
'Molekül' (molecule) is very often used as the second part of compound nouns to specify the type of molecule. Examples are 'Wassermolekül' (water molecule), 'Sauerstoffmolekül' (oxygen molecule), or 'Eiweißmolekül' (protein molecule).
Pflanzen produzieren bei der Fotosynthese Sauerstoffmoleküle.
Plants produce oxygen molecules during photosynthesis.
atom
An Atom is the smallest chemically indivisible building block of an element. A Molekül, by contrast, consists of at least two chemically bonded atoms. When a single building block of an element is meant, Atom is the right word; for a bonded unit made up of several atoms, Molekül is the right word.
Ein Molekül Sauerstoff besteht aus zwei gebundenen Sauerstoffatomen.
An oxygen molecule consists of two bonded oxygen atoms.
Ein einzelnes Atom Sauerstoff gehört zum Element Sauerstoff.
A single oxygen atom belongs to the element oxygen.
