검증된 단계별 안내1
Identify the element highlighted in the periodic table. The element is Selenium (Se).
Determine the period number of Selenium. Selenium is located in the 4th row of the periodic table, which corresponds to period 4.
Understand that the period number of an element corresponds to the principal quantum number (n) of the outermost shell of its electrons.
Recognize that the principal quantum number (n) indicates the shell number where the outermost electrons are located.
Conclude that for Selenium, the possible value for the shell number (n) is 4, as it is in period 4 of the periodic table.
