use the dot structure on the right and the periodic table to determine the element represented.\n sodium (na)\n potassium (k)\n neon (ne)\n argon (ar)\n done

Answer

Brief Explanations:

Count the number of electrons in the dot - structure. Sodium has 11 electrons, potassium has 19 electrons, neon has 10 electrons and argon has 18 electrons. By counting the dots representing electrons in the given structure and comparing with the electron - configurations of the elements from the periodic table, we can identify the element.

Answer:

If the structure has 18 electrons (2 in the first shell, 8 in the second shell and 8 in the third shell), the answer is argon (Ar). Without actually counting the dots precisely in the provided image, if we assume a correct 18 - electron configuration as per the typical noble - gas electron - shell filling pattern, the answer is D. argon (Ar)
