Neon is in period 2, so it has two main levels.
All three are filled: the configuration is 1s2, 2s2, 2p6. Neon's neutral atom has 10 protons and 10 electrons.
2 in the firts shell , 8 in the second . the electronic configuration is :-
1s2, 2s2, 2p6 The first and second shells are full.

eight
Period number = no. of electron shells. Therefore neon has two shells.
Yes. Helium, Xenon, and Neon have stable electron numbers (octette rule).
2, 8 is the electron configuration
Technetium has five electron shells.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
eight

there is 2 full electron levels in sodium!!
Mg 2+ Has the same electron configuration as neon. Two electrons lost to do this.

Neon has 10 electrons arranged as 2 electrons in the first energy level, and 8 electrons in the second energy level. This gives it a full outer shell, following the octet rule.
1 valence electrons 2 full outer shells (electron levels) 3 outer shells (electron levels)
Period number = no. of electron shells. Therefore neon has two shells.
It has 8 valence electrons.

Sodium would most like be the element with one more electron over neon.
