Concept explainers
Indicate the number of protons, neutrons, and electrons in each of the following species:
Interpretation: The numbers of protons, neutrons, and electrons in the givens nuclei areto be determined.
Concept introduction:
The number of neutrons in an atom is defined as the difference between the mass number and the number of protons.
The number of protons and electrons are the same for an uncharged nucleus, which is equal to the atomic number of an element.

Explanation of Solution
For
From the periodic table, the atomic number of nitrogen is
Thus, the number of protons is equal to the atomic number that is equal to
For
From the periodic table, the atomic number of sulfur is
Thus, the number of protons is equal to the atomic number that is equal to
For
From the periodic table, the atomic number of copper is
Thus, the number of protons is equal to the atomic number that is equal to
For
From the periodic table, the atomic number of strontiumis
Thus, the number of protons is equal to the atomic number that is equal to
