How are groups arranged on the periodic table?
The chemical elements are arranged in order of increasing atomic number. The horizontal rows are called periods and the vertical columns are called groups. This is because they have the same number of outer electrons and the same valency. An example of a group in the periodic table is the alkali metal group.
What is the IUPAC name for an element with atomic number 108 Class 11?
For element 108, the scientists proposed the name “hassium”. It is derived from the Latin name Hassia for the German state of Hesse where the institute is located. This name was proposed to IUPAC in a written response to their ruling on priority of discovery claims of elements, signed 29 September 1992.
What is the group of this element?
The vertical columns in a periodic table which are organized on the basis of the presence of electrons in the outermost shell are termed as a group. The elements in the same group show similar properties due to the similar electronic configuration of their atoms.
Is there an element 104?
rutherfordium (Rf), an artificially produced radioactive transuranium element in Group IVb of the periodic table, atomic number 104.
