Define a molecule and provide examples of homonuclear and heteronuclear molecules.
Define a molecule and provide examples of homonuclear and heteronuclear molecules.
A molecule is a group of two or more atoms held together by chemical bonds. An example of a homonuclear molecule is oxygen (O2), consisting of two atoms of the same element. An example of a heteronuclear molecule is water (H2O), composed of different elements (two hydrogen atoms and one oxygen atom).
In what contexts is the distinction between molecules and ions dropped, and how is the term 'molecule' often used in those contexts?
In what contexts is the distinction between molecules and ions dropped, and how is the term 'molecule' often used in those contexts?
In quantum physics, organic chemistry, and biochemistry, the distinction from ions is dropped, and the term 'molecule' is often used when referring to polyatomic ions.
How is the term 'molecule' used in the kinetic theory of gases, and what is the implication of this usage?
How is the term 'molecule' used in the kinetic theory of gases, and what is the implication of this usage?
In the kinetic theory of gases, the term 'molecule' is often used for any gaseous particle regardless of its composition. This relaxes the requirement that a molecule contains two or more atoms, as the noble gases are individual atoms.
What type of atoms or complexes connected by non-covalent interactions are typically not considered single molecules?
