What is the definition of isomers?Molecular formulaThe molecular formula is a quantitative and qualitative representation of the amount and type of atom that make up a molecular substance. Its molecular formula represents the real proportion in which the substance is in its base state and therefore...

What is DNA made of? DNA is made up of molecules called nucleotides. Each nucleotide contains three components: a phosphate group, which is one phosphorus atom bonded to four oxygen atoms; a sugar molecule; and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (...
Definition: By its classical definition, a molecule is the smallest particle of a substance that retains the chemical and physical properties of that substance. They are composed of two or more atoms, a group of like or different atoms held together by chemical forces. ...
In science, as in life, words often acquire meaning through usage rather than through definition. We use ‘species’ and ‘force’ without being troubled by their imprecision. The same can be said about ‘molecule’. For example, it has been defined as: ‘The simplest unit of a chemical ...
, James Maxwell defined atom and molecule: "An atom is a body which cannot be cut in two; a molecule is the smallest possible portion of a particular substance." Since molecules were named before their true nature was discovered, it led to what is now an inexact and debated definition....
so classifying things as molecules based on bond type was unwise. This has led to a very broad definition of molecule that is typically accepted and understood today—two or more atoms that are connected through chemical bonding with a fixed number of atomic nuclei. As mentioned above, all com...
