Elements between 57 and 70 belongs to the f group. Elements from La - Lu belongs to this group. These are called Lanthanides.These elements are Lanthanides. They are placed separately. They have different chemical properties.
Elements 57 to 70 are part of the lanthanide series in the periodic table. They are known as the lanthanides or rare earth elements, and include elements such as lanthanum, cerium, and praseodymium. These elements have unique properties and are commonly used in various technologies and applications.
Elements from atomic number 57 (Lanthanum) to 71 (Lutetium) are called the Lanthanides. Lanthanide means "like Lanthanum" and so, the Lanthanides are based on Lanthanum. Only one of the Lanthanides is radioactive: Promethium (Pm - No. 61)
Well, giving the example of Bromine (1s22s22p63s23p64s23d104p5) the s orbitals (represented by the letter s) are the first two groups/families (1-2) with the exception of helium, the p orbitals (represented by the letter p) are the last six groups/families (13-18), and the d orbitals (represented by the letter d) are the transition metals (3-12). Not included in bromine are the f orbitals (elements 57-70 and 89-102)
Yes, manganese is considered a representative element. It belongs to Group 7 (sometimes called Group 7B or 7A) of the periodic table, also known as the manganese family or the halogen group. Representative elements are those elements in the s and p blocks of the periodic table.
because they are man made.
These elements are termed as 'lanthanides' and 'actinides' have certain different characteristics that cannot be fitted into modern periodic table,hence they are placed at the bottom.
Elements 57 through 70 on the Periodic Table are part of the Lanthanide Series
The values 57 through 70 and 89 through 102 are often found separately at the bottom of a table because they correspond to additional data that may not fit in the main body of the table. Placing them separately at the bottom helps keep the table organized and allows for easier referencing of this additional information.
They are lanthanides and actinides. They have different chemical properties , hence they are placed separately.
elements 57 - 70.
Element 57 is Lanthanum and Element 70 is Ytterbium on the periodic table.

they are not placed from elements 57-70.
between Barium and Hafnium
Elements from atomic number 57 (Lanthanum) to 71 (Lutetium) are called the Lanthanides. Lanthanide means "like Lanthanum" and so, the Lanthanides are based on Lanthanum. Only one of the Lanthanides is radioactive: Promethium (Pm - No. 61)
