How Many Neutrons Does Zirconium(Zr) Have?

Answer:

zirconium(Zr) has 51 neutrons  for this isotope.

Explanation:

Hello, chemistry lover! today we are going to help you to find out how many neutrons zirconium(Zr)have in just 3 steps.

Description


Description


Descriptio







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



                    Step-1:



●The atomic number of 
 zirconium(Zr)  is the number of protons in zirconium(Zr)'s nucleus.



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


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



How Many Neutrons Does  zirconium(Zr) Have?




                    Step-2:

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





From periodic table,


  ●Atomic number of 
 zirconium(Zr) is 40.

●Atomic mass of  
zirconium(Zr) is 91.22

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


So,by rounding,we are getting mass number of  zirconium(Zr).The mass 
number of zirconium(Zr) is 91.



                    Step-3:

How Many Neutrons Does zirconium(Zr) Have?

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


●Number of neutrons=91-40=51

In another way,

●Mass number=Protons +Neutrons

Or,91 =40+Neutrons

Or,91-40=Neutrons

Therefore,
Neutrons=51


Therefore,the number of neutrons in zirconium(Zr) is 51 here for this isotope.Remember that neutrons are present in the nucleous of zirconium(Zr)and it's charge is zero.

●Number of protons in 
zirconium(Zr) is 40.Protons are present in the nucleus of zirconium(Zr) .



● Number of electrons in 
zirconium(Zr)  is 40.Remember that number of electron equals to proton in a neutral atom.Eletrons are present outside of nucleus of zirconium(Zr)  .
