if we find the electronic configuration, by 2n^2 rule, we can find it
8
One.Hydrogen has only 1 electron in total, and it is also a valence electron.
A silicon atom has 4 valence electrons and each hydrogen atom has one valence electron, for a total of 8.
No such thing as pi3, but if you mean PI3, then there are 5 valence electron in P, and each I has 7 valence electrons for a total of 5 + 7 + 7 + 7 = 26 valence electrons.
It has 4 valence electrons and a valence electron potential of 95.2
There are 7 valence electrons in chlorine.
For neutral atoms, the electron number is always the same as the proton number.For ions, charged atoms, the proton number is different than the electron number by the charge (e.g. a hydrogen ion, H(+1) has 1 proton and 0 electrons, 1 more proton than electrons).
group number
One valence electron.
The elements in Group 1 have one valence electron in their outermost s orbital.
7
It is 0.
