If there are more protons than electrons, an atomic ion has a positive charge and is called a cation. Elements are shown from atomic number 1 (hydrogen) up to 94 (plutonium). Since the inner electron level, 4f orbitals are successively filled from (4f 1 to 4f 14) though there are outer incompletely filled electron levels, these elements are called inner transition elements and the series are called inner transition series. Electron configurations describe where electrons are located around the nucleus of an atom. The amount of electrons in each shell and subshell is typically represented by a sequence of numbers and letters, such as 1s 2s 2 2p 6 , when describing the electronic configuration of an atom.
