C.periods C.Similar symbols
D.lines D.Similar masses
Vertical columns on the periodic table are called B. families.
The elements in each column, or family, have B. Similar properties.
In the periodic table, elements are organized into rows and columns based on their atomic number and electron configuration. Each vertical column represents a family or group of elements that share similar chemical and physical properties.
The elements within a family tend to have similar valence electron configurations, leading to similar chemical behaviors and reactivity patterns.
