Ruthenium(Ru) Have?
Hello, chemistry lover! today I am going to help you to find out how many neutrons ruthenium(Ru) have in just 3 steps.


Description


Description


Descriptio







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



                    Step-1:


●The atomic number of  ruthenium(Ru)  is the number of protons in ruthenium(Ru) nucleus.


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


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

                    Step-2:

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





From periodic table,


  ●Atomic number of  ruthenium(Ru) is 44.

●Atomic mass of  ruthenium(Ru) is 101.1

●To find out mass number,we need to round 101.1 to a whole number.

So,by rounding,we are getting mass number of  ruthenium(Ru).
The mass number of ruthenium(Ru) is 101.


                    Step-3:

How Many Neutrons Does ruthenium(Ru) Have?

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


●Number of neutrons=101-44=57

In another way,

●Mass number=Protons +Neutrons

Or,101 =44+Neutrons

Or,101-44=Neutrons

Therefore,
Neutrons=57





Therefore,the number of neutrons in ruthenium(Ru) is 57 here for this isotope.Remember that neutrons are present in the nucleous of ruthenium(Ru)and it's charge is zero.

●Number of protons in ruthenium(Ru) is 44.Protons are present in the nucleus of ruthenium(Ru) .



● Number of electrons in ruthenium(Ru)  is 44.Remember that number of electron equals to proton in a neutral atom.Eletrons are present outside of nucleus of ruthenium(Ru)  .

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 electron...
