The elements between group 2 and 13 are called Transition elements. They are placed in center of Periodic Table.
Special name given to groups in Transition metal.They have a lot of electrons and distribute them in different ways.Famous transition metals are Copper,Nickel and Zinc.
Group.
by their atomic number
They are called groups. The classic form indicates the 18 groups as 1A, 2A, 3B, 4B, 5B, 6B, 7B, three columns as 8B, 1B, 2B, 3A, 4A, 5A, 6A, 7A, and 8A (or 0). The IUPAC renumbered the groups as simply 1 to 18 in 1990. (see related link)
Moseley discovered modern periodic table. It was not given by Bohr.
No, the modern periodic table is not given by Niels Bohr. The modern periodic table was developed by Dmitri Mendeleev in 1869, while Niels Bohr is known for his contributions to the atomic model, explaining the behavior of electrons in atoms.
The middle 10 columns of the periodic table are known as the transition metals. These elements are characterized by their ability to form colored compounds and exhibit variable oxidation states. They are located between groups 3 to 12 on the periodic table.
Transition metals/nonmetals
Group.
The vertical columns are known as the groups. Elements in a given group have the same number of valence electrons and hence similar properties.
Elements in a vertical column on the periodic table are called groups or families.
The Illuminati is the name given to made up groups of people who claimed to have special knowledge of things.
The element in a given vertical column (or groups) have the same number of valence electrons and hence have similar properties.
I'm pretty sure that groups 3-12 (which includes 7) on the periodic table are classified as Metalloids.
The name given to group 7 elements in the Periodic table are halogens.
The name comes from the "periodic" (regularly arranged) traits of the material elements. The name given to the table's horizontal rows is periods.The Periodic Table is a tabular arrangement of the elements in increasing order oftheir atomic numbers, so that elements with similar properties are in the same column. There are 18 columns, called groups, and seven rows, which are called periods, in the modern periodic table.
Dmitri Mendeleev is given credit for the Periodic Table.
It's hard to say without all the information, but in general, no social group should be given special rights, but all social groups should have equal rights.
