Answer:
₁H³
Explanation:
Tritium is the isotope of hydrogen.
It consist of one proton two neutron and one electron.
It is rare isotope of hydrogen.
It is radioactive.
Its mass is 3.0160492 u.
In atmosphere it is also present in trace amount.
Its decay product is He³.
₁H³ → ³He₂⁺¹ + e⁻
Answer: The isotopic representation of tritium atom is [tex]_1^3\textrm{H}[/tex]
Explanation:
Isotopes are defined as the chemical species which have same atomic number but differ in mass number.
Hydrogen has 3 isotopes that occur naturally. They are: H-1 (protium), H-2 (deuterium) and H-3 (tritium)
The isotopic representation of an atom is: [tex]_Z^A\textrm{X}[/tex]
where,
Z = Atomic number of the atom
A = Mass number of the atom
X = Symbol of the atom
We know that:
Mass number of H-3 isotope = 3
Atomic number of H-3 isotope = 1
Hence, the isotopic representation of tritium atom is [tex]_1^3\textrm{H}[/tex]
