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


Description


Description


Descriptio







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



                    Step-1:


●The atomic number of  rhodium(Rh)  is the number of protons in rhodium(Rh) nucleus.


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


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



How Many Neutrons Does rhodium(Rh) Have?




                    Step-2:

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





From periodic table,


  ●Atomic number of  rhodium(Rh) is 45.

●Atomic mass of  rhodium(Rh) is 102.9

●To find out mass number,we need to round 102.9 to a whole number.

So,by rounding,we are getting mass number of  rhodium(Rh).
The mass number of rhodium(Rh) is 103.


                    Step-3:

How Many Neutrons Does rhodium(Rh) Have?

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


●Number of neutrons=103-45=58

In another way,

●Mass number=Protons +Neutrons

Or,103 =45+Neutrons

Or,103-45=Neutrons

Therefore,
Neutrons=58





Therefore,the number of neutrons in rhodium(Rh) is 58 here for this isotope.Remember that neutrons are present in the nucleous of rhodium(Rh)and it's charge is zero.

●Number of protons in rhodium(Rh) is 45.Protons are present in the nucleus of rhodium(Rh) .



● Number of electrons in rhodium(Rh)  is 45.Remember that number of electron equals to proton in a neutral atom.Eletrons are present outside of nucleus of rhodium(Rh)  .

Selenium has six valence electrons. Read:CO2 Lewis Structure Explanation: Now I am going to show you how to find valence electrons in selenium  in just 5 steps. Add caption              Step-1: First, find the atomic number of  selenium  from periodic table. From periodic table ,we see that the atomic number of  selenium  is 34.                  Step-2: We know that the atomic number of  selenium  is 34.So  selenium  has 34 protons and 34 electrons as the charge of electrons and protons are equal but opposite in nature.The charge of proton is +1 and the charge of electron is -1.

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

H₂SO₄ + NaOH ----->Na₂SO₄ +H₂O Step-2:In the left side, we have  H SO₄  Na O To balance this reaction means we need to equalize the number of these above atoms and polyatomic ion. Step-3:Now balance Na atom first.In the left hand side,we have one Na but in the right side,we have two Na.So to balance Na ,we need to put 2 before NaOH in the left side.
