Thechemical symbolfor Selenium isSe. Since d orbitals are always one shell behind s and p orbitals, and f orbitals are always two shells behind s and p, then it can be concluded that the highest shell number will always be for s and p orbitals, where the valence electrons reside. Its boiling point is the lowest among all the elements. These have similar chemical properties, but palladium has the lowest melting point and is the least dense of them.

In practice, chemists simplify the notation by using a bracketed noble gas symbol to represent the configuration of the noble gas from the preceding row because all the orbitals in a noble gas are filled. Most elements have more than one possible oxidation state. The first two columns on the left side of the periodic table are where thessubshells are being occupied. Gold is a transition metal and a group 11 element. We place one electron in the orbital that is lowest in energy, the 1s orbital. It is an extremely reactive element and a strong oxidising agent: among the elements, it has the highest electron affinity and the third-highest electronegativity, behind only oxygen and fluorine. Francium is a highly radioactive metal that decays into astatine, radium, and radon. We write electronic configurations by following the aufbau principle (from German, meaning "building up"). It is also the most corrosion-resistant metal, even at temperatures as high as 2000 C. Francium is the second-least electronegative element, behind only caesium, and is the second rarest naturally occurring element (after astatine). Some of these anomalies occur as the 3d orbitals are filled. Thechemical symbolfor Titanium isTi. It is by mass the most common element on Earth, forming much of Earths outer and inner core. Technetium is the lightest element whose isotopes are all radioactive; none are stable.
