Multiple Choice
Which group of elements on the periodic table is characterized by high stability and a lack of reactivity?
A
Halogens (Group 17)
B
Alkali metals (Group 1)
C
Noble gases (Group 18)
D
Transition metals (Groups 3-12)
Verified step by step guidance
1
Identify the groups of elements listed: Halogens (Group 17), Alkali metals (Group 1), Noble gases (Group 18), and Transition metals (Groups 3-12).
Recall that chemical reactivity is often related to the electron configuration, especially the valence electrons in the outermost shell of an atom.
Understand that elements with a full valence shell tend to be very stable and unreactive because they have little tendency to gain or lose electrons.
Recognize that Noble gases (Group 18) have a complete valence electron shell, which makes them highly stable and chemically inert under normal conditions.
Conclude that the group characterized by high stability and lack of reactivity is the Noble gases (Group 18).
