The periodic table of chemical elements, often called the periodic table, organizes all discovered chemical elements in rows (called groups) and columns (called periods) according to increasing atomic number. Scientists use the periodic table to quickly refer to information about an element, like atomic mass and chemical symbol. The periodic table’s arrangement also allows scientists to discern trends in element properties, including electronegativity, ionization energy, and atomic radius.

Oxygen is the 2nd most electronegative element. When you examine a periodic table, you will find that (excluding the noble gases) the electronegativity values tend to increase as you go to the right and up. The reverse statement is that the values tend to decrease going down and to the left.
