Unfortunately, it seems there has been a misunderstanding here. NeF6 is not an existing chemical compound. Ne is the symbol for Neon, a noble gas in group 18 on the periodic table. Neon has eight electrons in its outer shell and therefore, according to the octet rule, it does not participate in chemical reactions to form compounds.
Theoretically, if NeF6 existed, it would be a chemical compound consisting of a Neon atom linked with six Fluorine atoms. However, because Neon is a noble gas that does not participate in chemical reactions, NeF6 cannot be formed.
