How to approach the problem First, determine the number of electrons in an atom of scandium()%(17). Remember, shells don’t neatly stack on top of each other, so the valence may not be the same as the total number of electrons in the outer shell. Is it necessary for the first dot around an atomic symbol to go on a particular side of the atomic symbol? It is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds. 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.
