Where are the elements with the most valence electrons located on the periodic table?
A
In the transition metals in the center
B
At the bottom of the periodic table
C
In Group 1 (alkali metals) on the far left
D
In Group 18 (noble gases) on the far right
Verified step by step guidance1
Understand that valence electrons are the electrons in the outermost shell of an atom and determine the chemical properties of an element.
Recall that the periodic table is arranged in groups (columns) where elements in the same group have the same number of valence electrons.
Recognize that Group 1 elements (alkali metals) have 1 valence electron, and the number of valence electrons increases as you move from left to right across a period.
Identify that Group 18 elements, known as noble gases, have a full outer shell, meaning they have the maximum number of valence electrons for their period (usually 8, except for helium which has 2).
Conclude that elements with the most valence electrons are located in Group 18 on the far right of the periodic table.
