To find out the number of neutrons for antimony(Sb) ,we have to have knowledge about atomic number,atomic mass,mass number of antimony(Sb)
.Click picture to see clearly.
Step-1:
●The atomic number of antimony(Sb) is the number of protons in antimony(Sb) nucleus.
●The atomic mass of antimony(Sb) is the average number of protons plus neutrons of all the isotopes of antimony(Sb) .
●The masss number of antimony(Sb) is the number of protons plus neutrons of a specific isotope of antimony(Sb) .
Step-2:
We need to convert atomic mass of antimony(Sb) to mass number of antimony(Sb) by rounding if necessary (In case of fraction) .
From periodic table,
●Atomic number of antimony(Sb) is 51.
●Atomic mass of antimony(Sb) is 121.8
●To find out mass number,we need to round 121.8 to a whole number.
So,by rounding,we are getting the mass number of antimony(Sb).The mass number of antimony(Sb) (we are getting) is 122.
Step-3:
By the difference between mass number and atomic number of antimony(Sb),we get the number of neutrons in antimony(Sb).
●Number of neutrons=122-51=71
In another way,
●Mass number=Protons +Neutrons
Or,122 =51+Neutrons
Or,122-51=Neutrons
Therefore,
Neutrons=71
Therefore,the number of neutrons in antimony(Sb) is 71 here for this isotope.Remember that neutrons are present in the nucleous of antimony(Sb) and it's charge is zero.
●Number of protons in antimony(Sb) is 51.Protons are present in the nucleus of antimony(Sb) .
● Number of electrons in antimony(Sb) is 51.Remember that number of electron equals to proton in a neutral atom.Eletrons are present outside of nucleus of antimony(Sb) .
