Q: Is a molecule an electrically neutral group of two or more atoms held together by chemical bonds? ¶
Q: Is a molecule the two important factors that determine its properties? ¶
A: Yes, and particularly its reactivity.
Q: Are molecules far too small to be seen with the naked eye? ¶
A: Yes, but there are exceptions.
Q: Is a molecule often used less strictly? ¶
A: Yes, and also being applied to polyatomic ions.
Q: Are molecules held together by either covalent bonding or ionic bonding? ¶
Q: Is a molecule often used for any gaseous particle regardless of its composition? ¶
Q: Are molecules the hydrogen molecule-ion? ¶
A: Yes, and H2+, and the simplest of all the chemical bonds is the one-electron bond.
Q: Are molecules called molecular chemistry or molecular physics? ¶
A: Yes, and depending on whether the focus is on chemistry or physics.
Q: Are molecules macromolecules or supermolecules? ¶
Q: Is a molecule not a fundamental entity? ¶
A: Yes, rather, the concept of a molecule is the chemist's way of making a useful statement about the strengths of atomic-scale interactions in the world that we observe.
Q: Is a molecule inherently an operational definition? ¶
Q: Are molecules distinguished from ions by their lack of electrical charge? ¶
Q: Is a molecule used for very reactive species? ¶
A: Yes, and i.e., short-lived assemblies of electrons and nuclei, such as radicals, molecular ions, Rydberg molecules, transition states, van der Waals complexes, or systems of colliding atoms as in Bose–Einstein condensate.
