Question

Write 10 examples of diatomic element

Answer 1

They are the building blocks of any matter. Atoms are very tiny and small particles compare to anything that we can imagine or compare with. The radius of isolated neutral atom is in between 30 and 300 pm. No doubt an atom is an extremely small particle of matter but it always retains its identity during chemical reactions. There is a universal ways to symbolise all atoms. You must know that initially Latin was the common language of science, they were abbreviations based on the Latin names of metals, for example:Cu comes from CuprumFe comes from FerrumAg from ArgentumLater, the symbols of elements were based on the name of the element such as the chemical symbol for sodium is 'Na' after the Latin natrium
."Hg" (hydrargyrum)
for mercury"Sn" (stannum)
for tin"K" (kalium)
for potassium
Remember the first letter of a chemical symbol is always capitalized, as observed in the given examples, and the subsequent letters, if any, are always lower case (small letters). A molecule is made up of atoms. It is a group of atoms that are bonded by a chemical bond. The atoms are in a molecule are arranged in a regular pattern. Similar or different atoms combine together to form molecules. These atoms are boned together with the covalent bond or ionic bond in the molecule. The type of chemical bond depends upon the electronic configurations of constituent atoms such as the bond between metal and non-metal must be ionic whereas two non-metals are boned together with covalent bond.The number of atoms constituting a molecule is known as its atomicity. The only example of monoatomic molecule is Noble gas because they do not havetendency to form chemical bond with other atoms. Similarly di-atomic molecules consist of two similar or different atoms like the oxygen molecule (O2) or carbon monoxide (CO). Some other examples of diatomic molecules are N2 (N=N), F2 (F-F) and HF (H-F). Some molecules contain three atoms like the ozone molecule (O3). Hence, the number of atoms present in a molecule determines the atomicity of the molecule.Diatomic molecules can be two types; heteronuclear diatomic molecules and homonuclear diatomic molecules. Homonuclear diatomic molecules are made of two similar atoms such as Cl2, H2, N2, O2, F2 etc. On the contrary, heteronuclear diatomic molecules are composed of dissimilar atoms such asCO, HF, HCl, MgO, CO, NO, HBr and SiO.
