Write the electron configuration for Ne. Then write the Lewis symbol for Ne and indicate which electrons from the electron configuration are included in the Lewis symbol.
Verified step by step guidance1
Identify the atomic number of Neon (Ne), which is 10, indicating it has 10 electrons.
Write the electron configuration for Ne: Start by filling the 1s orbital, then the 2s orbital, and finally the 2p orbital until all 10 electrons are accounted for.
The electron configuration for Ne is: 1s^2 2s^2 2p^6.
Draw the Lewis symbol for Ne: Since Ne is a noble gas with a full outer shell, represent it with the element symbol 'Ne' surrounded by 8 dots, indicating the 8 valence electrons (2s^2 2p^6).
Explain that the Lewis symbol includes only the valence electrons, which are the electrons in the outermost shell (2s^2 2p^6) for Ne.
