Question 7SavedComplete the sentence.In the periodic table, elements with similar chemical properties occupy the same:

In the periodic table, elements with similar chemical properties occupy the same group. Groups are the vertical columns found in the periodic table, and they categorize elements that share similar valence electron configurations. This similarity in electron arrangements leads to consistent behavior when these elements undergo chemical reactions. For example, the elements found in Group 1, known as the alkali metals (such as lithium, sodium, and potassium), all have one valence electron and exhibit similar reactivity, particularly with water and halogens. Similarly, the halogens, found in Group 17, display similar properties due to their seven valence electrons, making them highly reactive non-metals. Thus, understanding groups in the periodic table aids in predicting the behaviors and reactivities of different elements based on their placement.
