Why is the periodic table organized into groups?
A
Elements in the same group have similar chemical properties due to having the same number of valence electrons.
B
Groups are organized based on increasing atomic mass.
C
Groups are arranged to separate metals from nonmetals.
D
Groups indicate the physical state of elements at room temperature.
Verified step by step guidance1
Understand that the periodic table is arranged in columns called groups or families.
Recognize that elements in the same group have the same number of valence electrons, which are the electrons in the outermost shell.
Know that valence electrons largely determine an element's chemical properties and reactivity.
Realize that because elements in the same group have the same number of valence electrons, they exhibit similar chemical behavior.
Therefore, the periodic table is organized into groups to reflect these similarities in chemical properties among elements.
