Description
To find out the number of neutrons for cerium(Ce),we have to have knowledge about atomic number,atomic mass and mass number of cerium(Ce).
.Click picture to see clearly.
Step-1:
●The atomic number of cerium(Ce) is the number of protons in cerium(Ce)'s nucleus.
●The atomic mass of cerium(Ce) is the average number of protons plus neutrons of all the isotopes of cerium(Ce) .
●The masss number of cerium(Ce) is the number of protons plus neutrons of a specific isotope of cerium(Ce) .
Step-2:
We need to convert atomic mass of cerium(Ce) to mass number of cerium(Ce) by rounding if necessary (In case of fraction) .
From periodic table,
●Atomic number of cerium(Ce) is 58.
●Atomic mass of cerium(Ce) is 140.1
●To find out mass number,we need to round 140.1 to a whole number.
So,by rounding,we are getting the mass number of cerium(Ce).The mass number of cerium(Ce) (we are getting) is 140.
Step-3:
By the difference between mass number and atomic
number of cerium(Ce),we get the number of neutrons in cerium(Ce).
●Number of neutrons=140-58=82
In another way,
●Mass number=Protons +Neutrons
Or,140 =58+Neutrons
Or,140-58=Neutrons
Therefore,
Neutrons=82
Therefore,the number of neutrons in cerium(Ce) is 82 here for this isotope.Remember that neutrons are present in the nucleous of cerium(Ce) and it's charge is zero.
●Number of protons in cerium(Ce) is 58.Protons are present in the nucleus of cerium(Ce) .
● Number of electrons in cerium(Ce) is 58.Remember that number of electron equals to proton in a neutral atom.Eletrons are present outside of nucleus of cerium(Ce) .
