Rn or Radon is a noble gas, and has 8 Valence Electrons
Lawrencium is a trivalent chemical element.
8 valence electrons (so do all of the other noble gases)
The possible electron configuration of hassium is [Rn]5f14.6d6.7s2.
There are no valence electrons.
Indium has 3 valence electrons.
On the outermost (or valence) electron shell.
Radon, being a noble gas, has 8 valence electrons, giving it a stable octet.
They give up two valence electrons to have a full electron shell.
helium has 2 valence electrons (in s orbital) and has complete s orbital. So it does not need to gain or lose more electrons to be stable.
its based on its electronic configration ..if it has 2 or 3 valance electrons it may attract electrones
There can be up to 18 valence electrons in a atom, these atoms are krypton, xenon, radon, and sometimes mentioned is ununoctium but is an "unknown element" so the element is not always mentioned
Lawrencium is a trivalent chemical element.
Radon has 8 valence electrons (electrons in it's outer shell) so does Ne, Ar, Kr, Xe. Helium is in the same line, but only has 2 valence electrons. Hope that helps! Sarah G.
cuando un atomo gana electrones
The noble gas configuration of francium is [Rn]7s^1, where [Rn] represents the electron configuration of radon, a noble gas element. Francium has one valence electron in the 7s orbital, making it highly reactive.
8 valence electrons (so do all of the other noble gases)
