o argon
o carbon
o neon

Explanation:

The atomic number is equal to the total number of electrons. For the electron - configuration $1s^{2}2s^{2}2p^{6}$, sum the electrons: $2 + 2+6=10$. Neon has an atomic number of 10. Argon has an atomic number of 18 and carbon has an atomic number of 6.

Answer:

neon
