What are the valence shell electron configurations of the elements in the first column of the periodic table?

Question

Quizplus · Accepted Answer

The elements in the first column of the periodic table are in the s-block and have a valence shell electron configuration of ns^1, where n represents the principal quantum number corresponding to the period in which the element is located. This configuration indicates that there is one electron in the s orbital of the valence shell. The other options include incorrect notations and do not accurately represent the valence electron configuration for elements in the first column of the periodic table.
