nothing they are just called groups.
Colunms are named 'Groups'. Rows are named 'Periods'.
Groups on the periodic table are called families because elements within the same group share similar chemical properties due to having the same number of valence electrons. This similarity in properties is what defines them as a family.
Families of elements with similar chemical properties are called "groups" or "families" on the periodic table. Elements within the same group typically have the same number of valence electrons, which gives them similar reactivity and chemical properties.
Because the elements that have similar properties are arranged in groups - or 'periods'.
They are called families because the elements in a group have similar properties.
Groups. Elements in the same group have similar electronegativity properties.
The properties of chemical elements have a periodic trend.
The columns in the periodic table are called groups or families. These columns contain elements with similar chemical properties due to their shared number of valence electrons.
Elements with similar properties are displayed in columns, called groups, on the periodic table. This arrangement allows elements with similar chemical behavior to be grouped together. Elements in the same group have the same number of valence electrons, which is the main factor determining an element's chemical properties.
The vertical elements are called groups. They have similar chemical properties.
Groups on the periodic table with similar properties are elements that have the same number of valence electrons. These elements tend to have similar chemical reactivity and often form similar types of compounds. For example, Group 1 elements (alkali metals) are highly reactive metals that readily lose their outer electron to form +1 ions.
The columns in the periodic table are groups, also called families because the elements in a group have similar properties.
