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. What would be the most likely charge of an ion formed from an atom with the electron configuration below 1s22s22p4 a. 2010 Best Answer Copy AlBr3 but it usually is found as the dimer Al2Br6 Wiki User. Atomic Mass of Caesium Atomic mass of Caesium is 132.9055 u. Mass numbers of typical isotopes of Caesium are 133. Isotopes are nuclides that have the same atomic number and are therefore the same element, but differ in the number of neutrons. Ionic radius, r ion, is the radius of a monatomic ion in an ionic crystal. For stable elements, there is usually a variety of stable isotopes.
