Periodic table row 8

WebElectron affinity of Boron is 26.7 kJ/mol. In chemistry and atomic physics, the electron affinity of an atom or molecule is defined as: the change in energy (in kJ/mole) of a neutral atom or molecule (in the gaseous phase) when an electron is added to the atom to form a negative ion. X + e– → X– + energy Affinity = – ∆H. WebIn general, the number of valence electrons is the same within a column and increases from left to right within a row.
