The three classes of periodic elements are:
There are 18 groups and 7 periods in the modern periodic table.
Groups in the periodic table are vertical columns that contain elements with similar chemical properties. Elements in the same group have the same number of valence electrons, which determines their reactivity and chemical behavior. There are 18 groups in the periodic table.
The 3 major groups are: # Metals - Groups 1-15 and the Inner Transitional Elements # Nonmetals - Groups 1 and 14-18 # Metalloids - Groups 13-17 (Diagonal strip of elements separating the metals from the nonmetals)
The elements that are listed in vertical columns all share specific aspects. These aspects include having the same number of valence electrons and having similar chemical properties.
A group in the periodic table is a column of elements that share similar chemical properties due to having the same number of electrons in their outer energy level. Groups are vertical columns and are numbered from 1 to 18.
There are 18 groups in the periodic table of elements.
There are 18 groups and 7 periods in the modern periodic table.
There are 18 groups in the Periodic Table of elements.
There are a total of 18 groups on The Periodic Table of Elements.
Elements are arranged on the periodic table based on their atomic number, which is the number of protons in their nucleus. This arrangement groups elements with similar properties in columns called groups or families, while elements in the same period have the same number of electron shells.
In the periodic table chemical elements are orderd in periods and groups.
All groups in the periodic table contain chemical elements.

There are 18 main groups in the modern periodic table of elements.
The Periodic Table of Elements
It is named The PERIODIC TABLE. The periods being the horizontal rows The groups being the vertical columns.
