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

Description


Description


Descriptio







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



                    Step-1:


●The atomic number of  niobium(Nb)  is the number of protons in niobium(Nb)'s nucleus.


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


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



How Many Neutrons Does niobium(Nb) Have?




                    Step-2:

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





From periodic table,


  ●Atomic number of  niobium(Nb) is 41.

●Atomic mass of  niobium(Nb) is 92.91

●To find out mass number,we need to round 92.91 to a whole number.

So,by rounding,we are getting mass number of  niobium(Nb)
.The mass n umber of niobium(Nb) is 93.



                    Step-3:

How Many Neutrons Does niobium(Nb) Have?

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


●Number of neutrons=93-41=52

In another way,

●Mass number=Protons +Neutrons

Or,93 =41+Neutrons

Or,93-41=Neutrons

Therefore,
Neutrons=52





Therefore,the number of neutrons in niobium(Nb) is 52 here for this isotope.Remember that neutrons are present in the nucleous of niobium(Nb)and it's charge is zero.

●Number of protons in niobium(Nb) is 41.Protons are present in the nucleus of niobium(Nb) .



● Number of electrons in niobium(Nb)  is 41.Remember that number of electron equals to proton in a neutral atom.Eletrons are present outside of nucleus of niobium(Nb)  .

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

Image
  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
