Question

Mention the difference between \[{{N}_{2}}\] and \[2N\,\]?

Answer 1

Hint: Atoms are single neutral particles. When we are just talking about the element, then using the symbol is pretty self-explanatory. Molecules are also neutral particles but it is made of two or more atoms bonded together.

Complete step by step solution:

* A molecule is defined as two or more atoms of the same element or of different elements that are bound together. A molecule can be of two types:
Homonuclear which means, it consists of atoms of one chemical element, as with oxygen (\[{{O}_{2}}\]).
Heteronuclear which is a chemical compound composed of more than one element, as with water (\[{{H}_{2}}O\])
* In the given question the difference between \[2N\,\] and \[{{N}_{2}}\] are:

\[2N\,\]	\[{{N}_{2}}\]
\[2N\,\] means two molecules of Nitrogen atom.	\[{{N}_{2}}\] means two atoms of nitrogen in its one molecule or we can also call it a diatomic molecule.
\[2N\,\] does not show any bond, it just shows that the number of nitrogens are two.	\[{{N}_{2}}\] shows that two nitrogen are bonded with covalent bonds, and it becomes nitrogen gas.
2N is a nascent nitrogen with no stability.	\[{{N}_{2}}\] is a stable molecule.

Note: An atom may not always be stable in nature as there is the presence of electrons in the outer shells whereas molecules are formed to attain stability. Except for the noble elements, atoms of all elements show a certain level of reactiveness when it is compared to a molecule, the level of reactivity is less as some of the valence points are filled by electrons of combined elements.
