Description
To find out the number of neutrons for barium(Ba),we have to have knowledge about atomic number,atomic mass and mass number of barium(Ba).
.Click picture to see clearly.
Step-1:
●The atomic number of barium(Ba) is the number of protons in barium(Ba)'s nucleus.
●The atomic mass of barium(Ba) is the average number of protons plus neutrons of all the isotopes of barium(Ba) .
●The masss number of barium(Ba) is the number of protons plus neutrons of a specific isotope of barium(Ba) .
Step-2:
We need to convert atomic mass of barium(Ba) to mass number of barium(Ba) by rounding if necessary (In case of fraction) .
From periodic table,
●Atomic number of barium(Ba) is 56.
●Atomic mass of barium(Ba) is 137.33
●To find out mass number,we need to round 137.33 to a whole number.
So,by rounding,we are getting the mass number of barium(Ba).The mass number of barium(Ba) (we are getting) is 137.
Step-3:
By the difference between mass number and atomic
number of barium(Ba),we get the number of neutrons in barium(Ba).
●Number of neutrons=137-56=81
In another way,
●Mass number=Protons +Neutrons
Or,137 =56+Neutrons
Or,137-56=Neutrons
Therefore,
Neutrons=81
Therefore,the number of neutrons in barium(Ba) is 81 here for this isotope.Remember that neutrons are present in the nucleous of barium(Ba) and it's charge is zero.
●Number of protons in barium(Ba) is 56.Protons are present in the nucleus of barium(Ba) .
● Number of electrons in barium(Ba) is 56.Remember that number of electron equals to proton in a neutral atom.Eletrons are present outside of nucleus of barium(Ba) .
