Concept explainers
(a)
Interpretation: The element needs to be determined for an atom with a mass number 88 and neutrons 50.
Concept Introduction:
For any element, the mass number is defined as the sum of the number of protons and neutrons in an atom; thus, the number of protons can be calculated.
Also, an
(b)
Interpretation: The number of neutrons in an isotope of the same element with mass number 86 needs to be determined.
Concept Introduction: For any element, the mass number is defined as the sum of the number of protons and neutrons in an atom thus, the number of protons can be calculated.
Also, an atomic number is equal to the number of protons and electrons in an atom.
For any
