Metals, Non-Metals and the ones that are both. :)
The periodic table of Mendeleev has 18 groups.
groups are the vertical columns on the periodic table
Groups of the Periodic Table are defined as vertical colums. There are 18 groups in the periodic table.
groups on the periodic table are the vertical coumns that go up and down. A period on the periodic table are the rows that go horizontal or across.
The group number tells you the number of valence electrons in the outer shell. This is important because it is the valence electrons that participate in bonding, and thus in determining the properties of the element.
- 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
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.
The periodic table of Mendeleev has 18 groups.
Periodic table can be classified as:MetalsTransition elementsNon-metalsThey occupy different groups.
groups are the vertical columns on the 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.
Groups of the Periodic Table are defined as vertical colums. There are 18 groups in the periodic table.
Elements are arranged on the Periodic Table in the order of the atomic number, in groups and periods.
Modern periodic table has 7 periods and 18 groups.
groups on the periodic table are the vertical coumns that go up and down. A period on the periodic table are the rows that go horizontal or across.
the vertical columns in the periodic table are known as groups.
Horizontal rows are called groups. Groups are formed according to the atomic number.
