Which of the following is incorrect statement with respect to protium, deuterium and tritium?
Option: 1
They are isotopes of Hydrogen
Option: 2
They have same electronic configuration
Option: 3
Their atomic mass is in the ratio 1 : 2 : 3 respectively
Option: 4
Naturally, they exist in the ratio of 1 : 2 : 3 respectively
Answers (1)
We know that protium, deuterium and tritium are isotopes of Hydrogen. They have only one electron so their electronic configuration is . They have only one proton but 0,1 and 2 neutron respectively. So, their atomic mass is in the ratio of
.
But it is not true that Tritium is three times abundant than protium or deuterium is two times abundant than protium. Natural abundances of hydrogen and deuterium are and
respectively and tritium is just traced.
