Although there is still some debate over the formal distinction, a molecule is a group of two or more atoms joined by chemical bonds, whereas a compound is a substance formed by the chemical bonding of more than one type of element that exists in a fixed proportion. Molecular compounds and ...
What is the difference between compound and atom? What does a molecule of a compound mean? (a) What is an atom? How do atoms usually exist?(b) What is a molecule? Explain with an example.(c) What is the difference between the molecule of an element and the molecule of a compound?
Molecule definition: the smallest physical unit of an element or compound, consisting of one or more like atoms in an element and two or more different atoms in a compound.. See examples of MOLECULE used in a sentence.
To put it simply, atoms are the most basic units of elements, or matter that cannot be chemically broken down further; and molecules are the most basic units of compounds, or matter that is made up of more than one element chemically bonded together. Chemical bonds occur through the sharing...

The terms molecule, compound, and atom can be confusing! Here's an explanation of what a molecule is with some examples of common molecules.
atom系一种element入面最细而且不能分割的部份,而Ion是由于atom/molecule得到或者失去electron时而令atom/molecule中的正负电荷失衡,得到净正或负电荷,咁ion都系element入面最细而且不能分割的部份?polyatomic ion系多过一个 atom 的 ion,咁他算不算系compound?
structure, capable of arranging a guest compound almost or entirely without reworking the guest compound, to provide a molecule-joining element comprising the compound, and to provide a host-guest mixture and a supramolecular chain structure, as the utilization of the molecule-joining element.DANJO...
