For this reason, the periodic table shows a trend in electronegativity. As you move across the periodic table from left to right, the electronegativity of the elements increases. As you move from bottom to top, the electronegativity also increases. It is important to note that the transition me...

Today, 150 years later, chemists officially recognize 118 elements (after the addition of four newcomers in 2016) and still use Mendeleev's periodic table of elements to organize them. The table starts with the simplest atom, hydrogen, and then organizes the rest of the elements by atomic numb...
Periodic table quiz The periodic table, also called the periodic table of elements, is an organized arrangement of the 118 known chemical elements. The chemical elements are arranged from left to right and top to bottom in order of increasing atomic number, or the number of protons in an at...
