QUESTION:
Indicate the number of protons, neutrons, and electrons in each of the following species:
\(_7^{15}\mathrm{N},\ _{16}^{33}\mathrm{S},\ _{29}^{63}\mathrm{Cu},\ _{38}^{84}\mathrm{Sr},\ _{56}^{130}\mathrm{Ba},\ _{74}^{186}\mathrm{W},\ _{80}^{202}\mathrm{Hg}\)
ANSWER:Step 1 of 8
Here, we are going to calculate the number of protons and the number of neutrons in the nucleus in the following elements.
We can determine the number of protons and the number of neutrons in the nucleus by the following equation.
Atomic number(Z) is defined as the total number of protons in an atom.
Mass number (A) is defined as the total number of protons and neutrons in an atom.
Mass number (A) = Number of proton + number of neutron
= Z + Number of neutron-----(1)
On the other hand, the number of protons and electrons are always same in an atom of an element.
Thus, the number of protons in an atom = the number of electrons in the same atom.
