Is it possiable for an atom or ion to have no valence electrons?

Answer 1

The term valance shell refers to the number of electrons in the outermost orbit so by taking that we can consider hydrogen has no valance electrons because the hydrogen atom has only two electrons and the first electronic orbit can hold that much number of electrons in it.

Answer 2

Yes, the one exception to the rule is the hydrogen ion, H+ (which is really just a proton), but in general, no since the valence sphere is the outer most shell of an atom that contains electrons. Therefore if there are no electrons it's no longer considered the valence shell, the outer most shell containing electrons is, also the noble gasses have no valency as they are all inert. and exist as single atoms with the expetion of xenon fluoride which was made under extreme conditons.

Answer 3

supplement An atom has to be the whole thing, nucleus and electron cloud. (in the Rutherford model)

If all the electrons were stripped off, then we'd have a fully ionized particle.

Remember, the concept of atom includes the use in chemistry. With no electrons, ordinary chemistry is precluded.

Answer 4

zero valent:having valency of zero

all noble gases or inert gases are zero valent like xenon=0 krypton=0

Answer 5

there would not be an element with zero valency, there is 8 valency, but you would not simply have a completely empty shell.

Hope this helped!
