Solution

The correct option is A $1 : 1 : 2$
The atomic number and the mass number of tritium are $1$ and $3$ respectively. Tritium contains $1$ electron, $1$ proton and $2$ neutrons.

Hence, the ratio of the number of electrons, protons, and neutrons in tritium is $1 : 1 : 2$ .

Lithium is a metal whose electronic configuration is 2 and 1 including 3 protons 3 electrons and 3 neutrons. So, if we remove 1 electron from lithium to make it stable. Then ,why would we call it lithium as it has 3 protons 3 electrons and 3 neutrons. But , after removal of 1 electron only 2 electrons are left. So, why would we call it lithium then.
