Question

What does the symbol ${{H}^{+}}$ convey?

Answer 1

The abbreviations used in chemistry for chemical elements, functional groups and chemical compounds are known as the chemical symbols. The element symbol for chemical elements is normally of one, two or three letters from their Latin or Greek alphabet and are written with the first letter capitalized.

Complete answer:
-Hydrogen is the chemical element with the symbol H, atomic number 1 and atomic weight 1.008.
-Hydrogen is the lightest element and is the most abundant chemical substance in the universe constituting approximately 75% of all baryonic mass.
-The variants of a particular chemical element which differ in neutron number and consequently nucleon number are known as isotopes of a chemical element.
-Hydrogen has the following isotopes-
$^{1}H\text{(Protium)}{{,}^{2}}H\text{(Deuterium)}{{,}^{3}}H\text{(Tritium)}{{,}^{4}}H{{,}^{5}}H{{,}^{6}}H{{,}^{7}}H$ .
$^{4}H{{,}^{5}}H{{,}^{6}}H{{,}^{7}}H$ are two highly unstable nuclei which are chemically synthesized and do not occur in nature.
-Ions are a part of chemistry forms from atoms and electrons that have either gained or lost their weight by the removal or addition of one or more valence electrons which will create either positive or negative charge.
-The ions with a negative charge are known as anions and the ion with a positive charge is known as a cation.
-Cations are positively charged ions which are formed when a metal or element loses its electrons. The loss of weight is by losing one or more than one electron and they do not lose any protons, therefore they develop a positive charge.
-Anions are negatively charged ions which are formed when non-metals or elements gain the electrons. The gain of weight is by accepting one or more than one electron but do not lose or gain any protons, therefore they develop a negative charge.
-Now from the concepts gained so far we can say that ${{H}^{+}}$ denotes a hydrogen cation which is formed by losing one electron.

Note:
You may get confused with some related terms such as- H, ${{H}_{2}},2H,\text{ and }2{{H}_{2}}$.
H represents just a single atom of hydrogen, which is known as Hydrogen element.${{H}_{2}}$symbol represents a hydrogen molecule which is the combination of two hydrogen atoms forming a single molecule of Hydrogen. 2H symbol represents two hydrogen atoms $2{{H}_{2}}$ symbol represents two moles of hydrogen molecules.
