Multiple Choice
Which of the following shell number values is a possible value for the element highlighted?
A
n = 10
B
n = 4
C
n = 6
D
n = 7
0 Comments
Verified step by step guidance1
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.
