The short form electron configuration of radium is: [Rn]7s2.
The element radium (atomic number 88) has the long term electron configuration 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 5s2 4d10 5p64f14 5d10 6s2 6p6 7s2 The electron configuration (short form) of radium is [Rn]7s2. It's configuration is also 2.8.18.32.18.8.2
Ra, radium
[Rn] 7s2 is the noble gas notation for radium. A link is provided to the Wikipedia article on radium.
Radium is a highly reactive element and does not typically exhibit a noble gas configuration. Noble gases have a full outer electron shell, which makes them stable and unreactive. Radium, on the other hand, is a highly radioactive element and is part of the alkaline earth metal group, so it tends to lose its outer electrons rather than achieve a noble gas configuration.
Rubidium has 5 electron shells. The electron configuration of rubidium is [Kr]5s1.
