To find out the number of neutrons  for  tellurium(Te) ,we have to have knowledge about atomic number,atomic mass,mass number of  tellurium(Te)
.Click picture to see clearly.



                    Step-1:



●The atomic number of 
 tellurium(Te)  is the number of protons in tellurium(Te)'s nucleus.



●The atomic mass of 
 tellurium(Te)   is the average number of  protons plus neutrons of all the isotopes of  tellurium(Te)   .


●The masss number of 
 tellurium(Te)  is the number of protons plus neutrons of a specific isotope of  tellurium(Te)   .

                    Step-2:

We need to convert atomic mass of 
 tellurium(Te)  to mass number of  tellurium(Te) by rounding if necessary (In case of fraction) .





From periodic table,


  ●Atomic number of 
 tellurium(Te) is 52.

●Atomic mass of  
tellurium(Te) is 127.6

●To find out mass number,we need to round 
127.6 to a whole number.


So,by rounding,we are getting mass number of  tellurium(Te).The mass number of tellurium(Te) is 128.



                    Step-3:

How Many Neutrons Does tellurium Have?

By the difference between mass number and atomic number of 
tellurium(Te),we get the number of neutrons in tellurium(Te).


●Number of neutrons=128-52=76

In another way,

●Mass number=Protons +Neutrons

Or,128 =52+Neutrons

Or,128-52=Neutrons

Therefore,
Neutrons=76





Therefore,the number of neutrons in tellurium(Te) is 76 here for this isotope.Remember that neutrons are present in the nucleous of tellurium(Te)and it's charge is zero.

●Number of protons in 
tellurium(Te) is 52.Protons are present in the nucleus of tellurium(Te) .



● Number of electrons in 
tellurium(Te)  is 52.Remember that number of electron equals to proton in a neutral atom.Eletrons are present outside of nucleus of tellurium(Te)  .
