Answer

Brief Explanations:

Sodium (Na) has an atomic number of 11. In long - hand electron configuration, electrons fill orbitals in the order of increasing energy. The first shell (n = 1) can hold 2 electrons (1s²), the second shell (n = 2) can hold 8 electrons (2s²2p⁶), and the remaining 1 electron goes into the 3s orbital (3s¹).

Answer:

1s²2s²2p⁶3s¹
