Question

Helium (He) and neon (Ne) are elements in Group 8A of the periodic table. How do the electron dot diagrams of these elements compare?

The electron dot diagram of helium has six fewer dots than the electron dot diagram of neon.
The electron dot diagram of helium has eight fewer dots than the electron dot diagram of neon.
Both the electron dot diagram of helium and the electron dot diagram of neon have two dots.
Both the electron dot diagram of helium and the electron dot diagram of neon have eight dots

Answer 1

The first statement is correct. Helium's Lewis dot diagram has 2 dots (one pair) while neon's has 8 dots, so helium has 6 fewer dots than neon.
