Answer

Explanation:

Step1: Recall sodium's atomic number

Sodium (Na) has an atomic number of 11, which means it has 11 electrons.

Step2: Analyze electron - shell capacities

The first shell (1s) can hold 2 electrons. The second shell has sub - shells 2s and 2p. The 2s sub - shell can hold 2 electrons and the 2p sub - shell can hold 6 electrons.

Step3: Determine the values of C, D, and E

After filling the 1s² (2 electrons), for the second shell, the 2s sub - shell is filled with 2 electrons (so C = 2), then the 2p sub - shell is filled with 6 electrons (so D = 6). After filling the first and second shells (2 + 2+6 = 10 electrons), the remaining 1 electron goes into the 3s sub - shell (so E = 1).

Answer:

C = 2 D = 6 E = 1
