Use the periodic table, find the neutral atom that has the same electron configuration as 1s2 2s2 2p6
a.)boron
b.)neon
c.)phosphorus
d.)carbon

Option B= neon

Explanation:

The given electronic configuration is of neon. Neon is noble gas with atomic number 10.  The noble gases configurations are used for abbreviated electronic configuration

For example, the atomic number of neon is ten and sodium is eleven. The abbreviated electronic configuration of sodium is written by using the neon abbreviation in following way:

The electronic configuration of neon is given below:

Ne₁₀ = 1s² 2s² 2p⁶

The abbreviated electronic configuration of sodium:

Na₁₁ = [Ne] 3s¹

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).
