Concept explainers
a.
Number of proton and number of neutron in each isotope.
a.
Answer to Problem 52A
Number of proton in both isotope is 27 and number of neutron in first isotope is 32 and in second 33.
Explanation of Solution
Given :
Formula used :
Where, A is mass number and Z is atomic number.
Calculation :
From periodic table atomic number of cobalt is,
Number of proton in any element is equal to atomic number.
Therefore, number of proton in both isotope will be 27.
Number of neutron in first isotope is equal to,
Number of neutron in second isotope is equal to,
Conclusion :
Therefore, number of proton in both isotope is 27 and number f neutron in first isotope is 32 and in second 33.
b.
Number of orbiting electron in each isotope.
b.
Answer to Problem 52A
Number of orbiting electrons in both isotopes will be, 27
Explanation of Solution
Given:
Atomic mass of both isotopes are,
Both the isotope are electrically neutral
Formula used :
For neutral atom.
Number of orbiting electrons = Z
Where, Z is atomic number
Calculation :
From periodic table atomic number of cobalt is,
Therefore, number of orbiting electron will be,
Number of orbiting electrons = Z =27
Conclusion :
Therefore, number of orbiting electrons in both isotopes will be, 27
