Question

Write the names of isotopes of hydrogen. What is the mass ratio of these isotopes?

Answer 1

Isotopes of Hydrogen:

• Hydrogen has three naturally occurring isotopes, which are indicated as ${}_1{}^1\mathrm{H}$ (Protium), ${}_1{}^2\mathrm{H}$(Deuterium), and ${}_1{}^3\mathrm{H}$(Tritium).

Mass ratio:

• The atomic mass of ${}_1{}^1\mathrm{H}$ = $1\mathrm{u}$
• The atomic mass of ${}_1{}^2\mathrm{H}$ = $2\mathrm{u}$
• The atomic mass of ${}_1{}^3\mathrm{H}$ = $3\mathrm{u}$
• Mass ratio = Atomic mass of ${}_1{}^1\mathrm{H}$ : Atomic mass of ${}_1{}^2\mathrm{H}$ : Atomic mass of ${}_1{}^3\mathrm{H}$.
• Mass ratio = $1:2:3$
