A tritium has 1 electron,1 proton and 2 neutrons
so if you are thinking tritium has 3 neutrons only that's wrong.
Morever if you are thinking of an isotope with 3 neutrons only you are going on the wrong way.
And also if you are looking for a substance composed of 3neutrons per nucleus its name is trineutron which is not detected.
Whatsoever the nucleus of a tritium also called triton has 2 neutrons and 1 proton
Look at the structure of an atom of tritium
And this is the nucleus of tritium atom also called triton
In a beta decay (
There are two down quarks and one up quark in a neutron. A free neutron is unstable and one downquark in it is converted in a upp quark releasing a W boson
Where d is the down quark
u is the upper quark
This is followed by the decay of W boson itself
One the down quark is converted to upp quark the neutron does not stay neutron any more. It changes into a proton because two upp quarks and 1 down quark make up a proton
Where u is representing one upp quark
d is representing one down quark
So this actually happens in a beta decay
Only one neutron is converted to a proton and no other neutrons are affected
So for the triton
1 neutron is being converted to a proton and releasing a W boson which decaying into an electron and electron antineutrino
Count how many neutrons and protons are there in triton
neutrons = 2
protons = 1
neutrons = 2-1 = 1
protons =1+1 = 2
Recognize the nucleus of the element with 2protons and 1electron.
Yes you figured it right,its a helium nucleus
So now time to represent the decay in an equation
H is hydrogen
He is helium
