Answer:
Based on the periodic table snippet provided, the element that is chemically similar to neon (Ne) is helium (He). Both neon and helium are noble gases, which are known for their chemical stability and low reactivity due to their complete outer electron shells.
Here's the reasoning:
Neon (Ne) is a noble gas located in group 18 (8A) of the periodic table.
Elements in the same group (column) tend to have similar chemical properties.
Helium (He) is the only other element from group 18 present in the given periodic table snippet.
Therefore, helium (He) is the element most chemically similar to neon (Ne) among the options provided.
