Question

choose the correct configuration for neon (ne). 7/10 1s2 2s2 2p6 3s2 3p6 1s2 2s2 2p6 3s2 1s2 2s2 2p6 1s2 2s1 2p6

Explanation:

Neon (Ne) is a noble - gas element with atomic number 10. Its electron configuration is determined by filling the electron shells according to the Aufbau principle. The first shell (n = 1) can hold 2 electrons (1s²), and the second shell (n = 2) can hold 8 electrons (2s²2p⁶). So the electron configuration of Ne is 1s²2s²2p⁶.

Answer:

1s²2s²2p⁶
