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
Silicon typically has four valence electrons and is neutral with no net charge. If it gains three additional valence electrons, it will have a total of seven valence electrons. This would result in a net charge of -3, as gaining electrons gives the atom a negative charge.
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.
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.
