Alloys Alloy is usually formed from two metals, it is formed of two metals or more with a certain ratio as iron alloys (ferromanganese, ferrochromium) and it may consist of metal and nonmetal with...
Iron Iron is the most important metal in heavy industries, Iron is the fourth most abundant element in earth’s crust after oxygen, silicon and aluminum as it forms (5.1 %) of the mass of...
Most of the transition elements are attracted to the external magnetic fields because the spin of unpaired electrons in the sublevel (d) produces a magnetic field that makes the atom attracted to the external...
The transition element is the element in which the orbitals of d or F are occupied with electrons but not completely filled either in its atomic state or in one of its oxidation states,...
The transition elements occupy the middle of the periodic table between (s) and (p) blocks, Including more than 60 elements (more than half the number of known elements), These elements can be classified into...
Elements are arranged in ascending order of their atomic number and according to their electronic configurations, the sequence of elements agrees with the Auf-bau principle, The long form periodic table is classified into 4 blocks...
