Question

Which of the following groups could be a distinguishable system?

Question 6 options:

a)	A group of electrons

b)	A group of helium atoms

c)	A group of protons

d)	A group of deuterium atoms

e)	A group of neutrons

Answer 1

to find we need to to two thing

fermions are indistinguishable and boson are distinguishable particle so  

first a group of electron can be distinguishable or indistinguishable depending upon the no of electron it is

even or odd

if even than distinguishable because wave function is symmetric if odd than wave function is antisymmetric so   indistinguishable

helium atom consist 2 electron 2 proton and 2 neutron   it will always is symmetric so it will distingishable always

group of proton

it will be both depending upon even or odd no of particles
