(a)
Interpretation:
The
Concept Introduction:
The number of protons indicates the atomic number of the element. It defines its characteristic place in the periodic table.
(b)
Interpretation:
The number of protons of nitrogen-13 and nitrogen-14 should be compared.
Concept Introduction:
The number of protons indicates the atomic number. It is present along with the neutrons in the nucleus of the atom. The protons are positively charged particles.
(c)
Interpretation:
The number of neutrons of nitrogen-13 and nitrogen-14 should be compared.
Concept Introduction:
The mass number is the total number of protons and neutrons present in the nucleus. Both constitute the mass of the element. Besides neutrons are neutrally charged particles.
(d)
Interpretation:
The mass number of nitrogen-13 and nitrogen-14 should be compared and the symbol of each isotope of nitrogen should be determined.
Concept Introduction:
The mass number is the total number of protons and neutrons present in the nucleus. Both added together will total to give mass of the element.
The isotope of any element is indicated by its atomic number and mass number. Both the numbers are displayed along with the element. The mass number is displayed as superscript while the atomic number is displayed as subscript as shown
