Concept explainers
Interpretation: The given table is to be completed.
Concept introduction: In a neutral atom, the number of electrons present are equal to protons. These two are also equivalent to the
The variation in number of neutrons causes variation in mass number. This results in isotopes of the elements.
Answer to Problem 44E
The complete table is shown below.
Symbol | Number of Protons in Nucleus | Number of Neutrons in Nucleus | Number of Electrons | Net Charge |
Explanation of Solution
In the symbol of an
The given sumbol of the isotope in the first row is
The atomic number is equivalent to number of protons, thus, the atomic number is
The formula used for the calculation of number of netutrons is shown below.
Substitute the value of number of netrons and atomic number of ion in the above formula.
In the second row, number of protons and neutrons is
The atomic number is equivalent to number of protons, thus, the atomic number is
The formula used for the calculation of mass number is shown below.
Substitute the value of number of netrons and atomic number of ion in the above formula.
Therefore, the atomic symbol for isotope is
In the third row, number of protons, electrons and neutrons is
The atomic number is equivalent to number of protons, thus, the atomic number is
The formula used for the calculation of mass number is shown below.
Substitute the value of number of netrons and atomic number of ion in the above formula.
Therefore, the atomic symbol for isotope is
The given sumbol of the isotope in the fourth row is
The atomic number is equivalent to number of protons, thus, the atomic number is
The formula used for the calculation of number of netutrons is shown below.
Substitute the value of number of netrons and atomic number of ion in the above formula.
In the fifth row, number of protons, electrons and neutrons is
The atomic number is equivalent to number of protons, thus, the atomic number is
The formula used for the calculation of mass number is shown below.
Substitute the value of number of netrons and atomic number of ion in the above formula.
Therefore, the atomic symbol for isotope is
In the sixth row, number of protons and neutrons is
The atomic number is equivalent to number of protons, thus, the atomic number is
The formula used for the calculation of mass number is shown below.
Substitute the value of number of netrons and atomic number of ion in the above formula.
Therefore, the atomic symbol for isotope is
Thus, the complete table is shown below.
Symbol | Number of Protons in Nucleus | Number of Neutrons in Nucleus | Number of Electrons | Net Charge |
