Cadmium(Cd) Have?




Hello, chemistry lover! today I am going to help you to find out how many neutrons cadmium(Cd) have in just 3 steps.

Descriptio







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



                    Step-1:



●The atomic number of 
 cadmium(Cd)  is the number of protons in cadmium(Cd) nucleus.



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


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

                    Step-2:

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





From periodic table,


  ●Atomic number of 
 cadmium(Cd) is 48.

●Atomic mass of  
cadmium(Cd) is 112.4

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


So,by rounding,we are getting the  mass number of cadmium(Cd).The mass number of cadmium(Cd) (we are getting) is 112.




                    Step-3:

How Many Neutrons Does cadmium  Have?

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


●Number of neutrons=112-48=64

In another way,

●Mass number=Protons +Neutrons

Or,112 =48+Neutrons

Or,112-48=Neutrons

Therefore,
Neutrons=64





Therefore,the number of neutrons in cadmium(Cd) is 64 here for this isotope.Remember that neutrons are present in the nucleous of cadmium(Cd) and it's charge is zero.

●Number of protons in 
cadmium(Cd) is 48.Protons are present in the nucleus of cadmium(Cd) .





● Number of electrons in 
cadmium(Cd)  is 48.Remember that number of electron equals to proton in a neutral atom.Eletrons are present outside of nucleus of cadmium(Cd)  .
