use the dot structure on the right and the periodic table to determine the element represented. sodium (na) potassium (k) neon (ne) argon (ar) done
Answer
Explanation:
Step1: Count electron - shell electrons
The first shell has 2 electrons, the second has 8, and the third has 8.
Step2: Calculate total electrons
$2 + 8+8=18$ electrons.
Step3: Match with periodic table
Elements have the same number of protons as electrons (in neutral state). Argon has 18 protons.
Answer:
argon (Ar)
