The element with atomic number 10 is neon (Ne). Neon has a total of 10 electrons, which are distributed among its atomic shells as follows:
1st shell: 2 electrons 2nd shell: 8 electrons
The electron configuration of neon is 1s² 2s² 2p⁶, indicating that the first shell (1s) is completely filled with 2 electrons, and the second shell (2s and 2p) is also completely filled with 8 electrons.
