Multiple Choice
Which group of elements on the periodic table is known for having similar chemical behavior due to their valence electron configuration?
A
Halogens (Group 17)
B
Noble gases (Group 18)
C
Alkali metals (Group 1)
D
Transition metals (Groups 3-12)
Verified step by step guidance
1
Understand that elements in the same group (vertical column) of the periodic table have similar chemical properties because they have the same number of valence electrons.
Recall that valence electrons are the outermost electrons of an atom and largely determine how an element reacts chemically.
Identify the groups mentioned: Halogens (Group 17), Noble gases (Group 18), Alkali metals (Group 1), and Transition metals (Groups 3-12).
Recognize that Alkali metals (Group 1) all have one valence electron, which makes them highly reactive and gives them similar chemical behavior.
Conclude that the group known for similar chemical behavior due to their valence electron configuration is the Alkali metals (Group 1).
