Neon's atomic number is 10. Thus, to be neutral, it must have 10 protons and 10 electrons. The first 10 electrons are filled into orbitals as 1s2 2s2 2p6.
A noble gas electron configuration involves representing an element's electron configuration by using the electron configuration of the nearest noble gas preceding it in the periodic table, followed by the remaining electron configuration for that element. For example, the noble gas electron configuration for sodium (Na) is [Ne] 3s¹, where [Ne] represents the electron configuration of neon leading up to sodium.
2, 8 is the electron configuration
Neon's long electron configuration is 1s2 2s2 2p6.
Oxide ion (O²⁻) has the electron configuration of a noble gas neon (Ne), which is 1s² 2s² 2p⁶.
Argon has the same electron configuration as N3. Both have 10 electrons with the electron configuration 1s2 2s2 2p6.

A neutral sodium atom must lose one electron to have the electron configuration of neon, which has a stable electron configuration with a full outer shell. Sodium typically forms a +1 cation by losing this one electron to achieve a stable configuration like neon.
Helium's electron configuration is 1s2. Neon's electron configuration is 1s22s22p6. All of the rest of the noble gases, like neon, have the maximum number of electrons in their outermost s and p orbitals (valence shells), which is eight.
If you mean 1s22s22p3, you would refer to the periodic table. Using 2p3, you would look at the second period (row), look at the p block, and count 3 elements to the right to find nitrogen.
Sodium has the electron configuration of neon.
If a sodium atom loses an electron to become a Na+ ion, its electron configuration will be the same as neon (1s22s22p6). Both sodium and neon have stable electron configurations.
When aluminum (Al, #13) reacts, it loses its three valence electrons to achieve the same electron configuration as neon (Ne, #10.) That configuration is 1s22s22p6. So yes, Al+3 has the same configuration as neon.
Magnesium will lose 2 electrons to have the same electron configuration as Neon. Neon has a full valence shell with 8 electrons, and Magnesium has 2 valence electrons. By losing 2 electrons, Magnesium can achieve a full valence shell and the same electron configuration as Neon.
2, 8 is the electron configuration
Neon's long electron configuration is 1s2 2s2 2p6.
The correct full electron configuration for neon (Ne) is 1s2 2s2 2p6.
Oxide ion (O²⁻) has the electron configuration of a noble gas neon (Ne), which is 1s² 2s² 2p⁶.
