Document Summary
When cation is formed from an atom of a transition metal, electrons are always removed first from the ns orbital (furthest from the nucleus) and then from the (n-1)d orbitals. Take out the outermost (highest number in front of the letters) Inner electrons cancel out positive charge. whatevers left is whats felt by each. Increases from right to left, top to bottom outer electron. Ion"s radius are smaller than atomic radius. Cation is always smaller than the atom it forms. Anion is always larger than the atom it forms. Ionization energy: minimum energy required to remove an electron from a gaseous atom together) The smaller the radii, the more energy needed to take an electron out aka higher the ionization energy needed. Ionization energy increases from left to right, bottom to top. Electron affinity: negative of the energy charge that occurs when an electron is accepted by an atom in the gaseous state to form an anion.
