Concept explainers
a)
Interpretation:The atomic depiction of T4822i should be drawn.
Concept introduction:The nuclide symbol of an atom is represented as follows:
XAZ
Where,
- Z is an
atomic number . - A is the mass number.
- Xis the isotope of any element.
The atomic number is number of protons present in the nucleus.Number of electrons is same as number of protons to maintain neutrality.
The formula to calculate number of neutrons in XAZ is as follows:
Number of neutron(N)= Mass Number(A)−Number of protons(Z)
b)
Interpretation: The atomic depiction of S7934e should be drawn.
