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

To find out the number of neutrons for neodymium(Nd),we have to have knowledge about atomic number,atomic mass and mass number of neodymium(Nd).


.Click picture to see clearly.



                    Step-1:


●The atomic number of  neodymium(Nd)  is the number of protons in neodymium(Nd)'s nucleus.


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


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



How Many Neutrons Does neodymium(Nd) Have?




                    Step-2:

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





From periodic table,


  ●Atomic number of  neodymium(Nd) is 60.

●Atomic mass of  neodymium(Nd) is 144.2

●To find out mass number,we need to round 144.2 to a whole number.

So,by rounding,we are getting the mass number of neodymium(Nd).The mass number of neodymium(Nd) (we are getting) is 144.




                    Step-3:

How Many Neutrons Does neodymium(Nd) Have?


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


●Number of neutrons=144-60=84

In another way,

●Mass number=Protons +Neutrons

Or,144 =60+Neutrons



Or,144-60=Neutrons



Therefore,
Neutrons=84




Therefore,the number of neutrons in neodymium(Nd) is 84 here for this isotope.Remember that neutrons are present in the nucleous of neodymium(Nd) and it's charge is zero.



●Number of protons in neodymium(Nd) is 60.Protons are present in the nucleus of neodymium(Nd) .











● Number of electrons in neodymium(Nd) is 60.Remember that number of electron equals to proton in a neutral atom.Eletrons are present outside of nucleus of neodymium(Nd) .

SO2 Lewis Structure   Answer: Here is the definition of SO2 Lewis structure. SO2 Lewis structure (sulfur dioxide electron dot structure) is that type of diagram where we show the total 18 valence electrons of SO2 as dots , or dots and dashes(-).In Lewis structure,it is common that a bonding pair of two electrons can be shown by  dash(-) or dots(●●) but a lone pair of two electrons is shown by dots[●●]. In SO2 Lewis structure,there are two double bonds that are going from the atom sulphur to oxygens. In SO2 Lewis structure ,there are totally five lone pairs of electrons.The each  oxygen has two lone pairs of electrons and the sulphur atom has one lone pair of electrons. In SO2 Lewis structure ,the oxygen atoms follow the octet rule but the sulfur atom don't follow the octet rule.It has more than eight electrons. In SO2 Lewis structure,we get nine pairs of electrons.Out of nine pairs of electrons,SO2 has four bond pairs of electrons and five lone pairs of electrons.Here,each oxy

  How many valence electrons does C6H12O6 (glucose) have ? Answer : In  C₆H₁₂O₆ ,we get 6 carbon atoms , 12 hydrogen atoms and 6 oxygen atoms. Firstly, carbon is an element of group 4A,so it has 4 valence electrons. Secondly,Hydrogen is an element of group 1A.So it has one valence electrons. Thirdly, oxygen is an element of group 6A .So it has six valence electrons. For   C₆H₁₂O₆ , 6 C = 6 × 4 = 24 12 H =12 × 1 =12 6 O = 6 ×6    = 36 Totally, we are getting 24 + 12 + 36 = 72 valence electrons in glucose (C6H12O6). Next
