The Periodic Table of Elements ELEMENTS IN SAME COLUMN (GROUP) HAVE SIMILAR CHEMICAL PROPERTIES. The name of each element (in brown) is accompanied by its chemical symbol (in red), as well as its atomic number Z and its most common (or most stable) mass number A. Z = atomic number = number of protons in the nucleus = number of electrons orbiting the nucleus;

اقرأ أكثر‣ Where are the rare earth elements on the periodic table? The scandium (Sc) is in the fourth row, yttrium (Y) is in the fifth row, and the rest of the rare earth elements are in the sixth row of the periodic table. ‣ Is indium a rare earth? Indium is a post transition metal, not a rare earth metal.
اقرأ أكثرThe periodic table, also known as the periodic table of (the) chemical elements, is a tabular display of the chemical elements.It is widely used in chemistry, physics, and other sciences, and is generally seen as an icon of chemistry.It is a graphic formulation of the periodic law, which states that the properties of the chemical elements exhibit a periodic dependence on their atomic numbers.

اقرأ أكثرThe Periodic Table we use today closely resembles that drawn up by Mendeleev. A modification of the Periodic Table was made following the work of Rutherford and Moseley. It was realized that the elements should be arranged in the order of atomic number, i.e. the number of protons in the nucleus. In the Modern Periodic Table (Figure

اقرأ أكثرThe long table you found looks like that for a several reasons. The trends going down Sc-Y-La are like those seen in groups 1 and 2. The trend going down Sc-Y-Lu is like that of groups 4 to about 10. Since lanthanide chemistry is basically that of trivalent alkali or alkaline earth metals, this tips the balance in favour of group 3 as Sc-Y-La.
