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.
In the periodic table chemical elements are orderd in periods and groups.
All groups in the periodic table contain chemical elements.
The properties of chemical elements have a periodic trend.
Groups of the Periodic Table are defined as vertical colums. There are 18 groups in the periodic table.
atomic number Chemical elements are organized in the form of the periodic table of Mendeleev, in groups and periods.
The periodic table of Mendeleev contain now 118 chemical elements arranged in groups and periods.
- the periodic table is organized in periods and groups- chemical elements are listed in the order of the atomic number- the periodic table obey the law of periodicity
Colunms are named 'Groups'. Rows are named 'Periods'.
groups are the vertical columns on the periodic table
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.
It is named The PERIODIC TABLE. The periods being the horizontal rows The groups being the vertical columns.
