What element has the electron configuration 7s2?
Ra, radium
What is the periodic symbol for radon?
[Rn] 7s2 is the noble gas notation for radium. A link is provided to the Wikipedia article on radium.
What is the noble gas configuration of 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.
How many electron shells does radium have?
Rubidium has 5 electron shells. The electron configuration of rubidium is [Kr]5s1.
What is the long electron configuration for radium?
The short form electron configuration of radium is: [Rn]7s2.

Rubidium has 5 electron shells. The electron configuration of rubidium is [Kr]5s1.
What the oxidation number for Ra?
The oxidation number for Ra (Radium) is +2. Radium tends to lose two electrons to achieve a stable electron configuration.
What is the long electron configuration for radium?
The short form electron configuration of radium is: [Rn]7s2.
Write the expected ground-state electron configuration for the alkaline earth metal after radium?
You think probably at Unbinilium (120Ubn) an element not still obtained. The supposed electron configuration of Ubn will be [Uuo]7s2.
How many core electrons in Ra?
There are 86 core electrons in radium (Ra), which is the number of electrons in filled inner electron shells. Radial's electron configuration is [Rn] 7s2, where [Rn] represents the electron configuration of radon (Rn) as the previous noble gas element.
Which is more reactive uranium radon or radium?
Radium is more reactive than radon. Radium is a highly reactive metal that readily forms compounds, while radon is a noble gas and is less reactive due to its stable electron configuration.
How many valence shells in radium?
Radium has seven electron shells; the valence of radium is 2+.
