Question

For each representation of a nucleus through, write the atomic symbol and identify which are isotopes. $\left(4.4,4.5\right)$

Short answer

B has the same number of protons as D and C has the same number of protons as E. SO B and D are Isotopes and C and E are Isotopes.

Step-by-step solution

Part (a) step 1: Given Information

We need to write the atomic symbol and identify which are isotopes or not.

Part (a) step 2: Simplify

From the diagram-

Number of protons $\left(P_A\right)=4$

Number of neutrons $\left(N_A\right)=5$

$$\begin{gathered} P_B=5 \\ {P}_C=6 \\ {P}_D=5 \\ {P}_E=6 \end{gathered}$$

Isotopes- One of two or more atoms that have the same atomic number(the same number of protons) but a different of neutrons.

No other element has the same number of protons as A, therefore, is no isotope of A.

Part (b) step 1: Given Information

We need to write the atomic symbol and identify which are isotopes or not.

Part (b) step 2: Simplify

From the diagram-

Number of protons $\left(P_A\right)=4$

Number of neutrons $\left(N_A\right)=5$

$$\begin{gathered} P_B=5 \\ {P}_C=6 \\ {P}_D=5 \\ {P}_E=6 \end{gathered}$$

Isotopes- One of two or more atoms that have the same atomic number(the same number of protons) but a different of neutrons.

B has the same number of proton as D. B and D are Isotopes.

Part (c) step 1: Given Information

We need to write the atomic symbol and identify which are isotopes or not.

Part (c) step 2: Simplify

From the diagram-

Number of protons $\left(P_A\right)=4$

Number of neutrons $\left(N_A\right)=5$

$$\begin{gathered} P_B=5 \\ {P}_C=6 \\ {P}_D=5 \\ {P}_E=6 \end{gathered}$$

Isotopes- One of two or more atoms that have the same atomic number(the same number of protons) but a different of neutrons.

C has the same number of protons as E. C and E are Isotopes.

Part (d) step 1: Given Information

We need to write the atomic symbol and identify which are isotopes or not.

Part (d) step 2: Simplify

From the diagram-

Number of protons $\left(P_A\right)=4$

Number of neutrons$\left(N_A\right)=5$

$$\begin{gathered} P_B=5 \\ {P}_C=6 \\ {P}_D=5 \\ {P}_E=6 \end{gathered}$$

Isotopes- One of two or more atoms that have the same atomic number(the same number of protons) but a different of neutrons.

B has the same number of nucleus as D. B and D are Isotopes.

Part (e) step 1: Given Information

We need to write the atomic symbol and identify which are isotopes or not.

Part (e) step 2: Simplify

From the diagram-

Number of protons $\left(P_A\right)=4$

Number of neutrons $\left(N_A\right)=5$

$$\begin{gathered} P_B=5 \\ {P}_C=6 \\ {P}_D=5 \\ {P}_E=6 \end{gathered}$$

Isotopes- One of two or more atoms that have the same atomic number(the same number of protons) but a different of neutrons.

C has the same number of protons as E. C and E are Isotopes.
