The atomic numbers and mass numbers of the nuclei of hydrogen, deuterium and tritium, respectively are in the ratio
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 1:1:1 and 1:2:3
Hydrogen (H): atomic number = 1, mass number = 1
Deuterium (D): atomic number = 1, mass number = 2
Tritium (T): atomic number = 1, mass number = 3
Ratio of atomic numbers: $1:1:1$
Ratio of mass numbers: $1:2:3$
Atomic numbers : 1:1:1, Mass numbers : 1:2:3
