These names are the names of chemical elements.
The transition metals are the most common, and are found in the middle (groups 3-12) of the periodic table.
There are 18 groups and 7 periods in the modern periodic table.
The columns on a periodic table are called "groups" or "families." Groupings are based on the number of valence electrons elements within the same group have in common, which influences their chemical properties.

Although groups are the most common way of classifying elements, there are some regions of the periodic table where the horizontal trends and similarities in properties are more significant than vertical group trends.

These names are the names of chemical elements.
Two names for columns on the periodic table are groups and families. These columns group together elements with similar chemical properties due to their shared number of valence electrons.
the vertical columns in the periodic table are known as groups.
