For example, tellurium comes before iodine in the periodic table, even though its atomic mass is slightly greater. Such anomalies are due to the relative abundance of the "isotopes" or varieties of each element. All the isotopes of a given element have the same number of protons, but differ...
The periodic table is a clean arrangement of all elements discovered so far. The elements are arranged from left to right in ascending order of their atomic numbers or the number of protons or electrons they contain. The elements are divided into four categories: main group elements, transition...
