Question

1. use the isotope graph to find the isotopes described here. in each case, give the isotope name and the isotope symbol.

a. find three isotopes with equal numbers of neutrons and protons.
b. find two isotopes with the same number of protons.
c. find two isotopes with the same number of neutrons.
d. find two isotopes with the same atomic mass units.

Explanation:

Step1: Analyze part a

Since we don't have the actual isotope - graph, we assume a general knowledge approach. For isotopes with equal numbers of neutrons and protons, common examples are Hydrogen - 2 (Deuterium), symbol $\ce{^2_1H}$; Carbon - 12, symbol $\ce{^12_6C}$; Oxygen - 16, symbol $\ce{^16_8O}$.

Step2: Analyze part b

Two such isotopes could be Hydrogen - 2 (Deuterium) $\ce{^2_1H}$ and Helium - 4 $\ce{^4_2He}$.

Step3: Analyze part c

Isotopes of the same element have the same number of protons. For example, Carbon - 12 $\ce{^12_6C}$ and Carbon - 14 $\ce{^14_6C}$.

Step4: Analyze part d

For isotopes with the same number of neutrons, consider Chlorine - 35 $\ce{^35_17Cl}$ (18 neutrons) and Argon - 36 $\ce{^36_18Ar}$ (18 neutrons).

Answer:

a. Hydrogen - 2 (Deuterium) $\ce{^2_1H}$, Carbon - 12 $\ce{^12_6C}$, Oxygen - 16 $\ce{^16_8O}$
b. Hydrogen - 2 (Deuterium) $\ce{^2_1H}$, Helium - 4 $\ce{^4_2He}$
c. Carbon - 12 $\ce{^12_6C}$, Carbon - 14 $\ce{^14_6C}$
d. Chlorine - 35 $\ce{^35_17Cl}$, Argon - 36 $\ce{^36_18Ar}$
