Question

if three neutrons are added to the nuclei of 235/92 U the new particle have an atomic number of

Answer 1

The new particle would have the same atomic mass after adding the three neutrons will be 92 + 3 = 95 u.



Explanation:

The proton present in the nucleus of an atom tells the atomic number of the atom.

The neutrons present there provide mass along woth the proton but play no role in changing the atomic number.


So adding more neutron will increase it's mass .

Answer 2

given as element u has so 235 atomic mass number and 92 as atomic number if three neutrons are added to the nucleui as we know nuclei contain protons plus neutrons and here neutrons are 143 II if three neutrons are added here it will become 146 neutrons and accordingly to get 146 neutron we have to add + 3 to the atomic number by which we get 95 and 95 is the atomic number now when we subtract 235 - 95 we would get the new number of neutrons which are 146
