The electron configuration of an element is 1s22s22p6. describe what most likely happens when an atom of this element comes near an atom having seven valence electrons. asap

Nothing will happen.

The atom with electron configuration 1s² 2s²2p⁶ is neon. It has a complete valence shell and is the least reactive of the noble gases.

An atom with seven valence electrons is in Group 17 and is a halogen. Even fluorine, the most reactive halogen, will not react with neon.

yeah ^ hes right. The electron configuration 1s² 2s²2p⁶ is neon. it won't react not even the most reactive halogen would react with neon. only because neon has the least reactive of all the gases.
