Based on the periodic chart shown which element would you expect to have a full valence shell lithium calcium neon or sulfur?

Based on the periodic chart, neon would be expected to have a full valence shell. Neon is a noble gas located in Group 18, which is characterized by having a complete outer shell of electrons, making it stable and non-reactive. In contrast, lithium, calcium, and sulfur do not have full valence shells.
