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.
One.Hydrogen has only 1 electron in total, and it is also a valence electron.
Xenon has 8 valence electrons.
A silicon atom has 4 valence electrons and each hydrogen atom has one valence electron, for a total of 8.
The valence electron configuration of oxygen is 2s2 2p4. Oxygen has 6 valence electrons in total, with 2 in the 2s orbital and 4 in the 2p orbital.
Hydrogen doesn't really have a valence shell. It has one electron only.
One.Hydrogen has only 1 electron in total, and it is also a valence electron.
Xenon has 8 valence electrons.
Hydrogen has only one electron. Just the one. And it is a valence electron.
A silicon atom has 4 valence electrons and each hydrogen atom has one valence electron, for a total of 8.
The valence electron configuration of oxygen is 2s2 2p4. Oxygen has 6 valence electrons in total, with 2 in the 2s orbital and 4 in the 2p orbital.
Francium has 87 electrons; one is the valence electron.
Hydrogen doesn't really have a valence shell. It has one electron only.
The element with a valence electron configuration of 3s^2 3p^4 is sulfur (S), which has 16 electrons in total.
Potassium has 19 total electrons and one electron in its 4th energy level.
Potassium (K) has 1 valence electron and Bromine (Br) has 7 valence electrons. Therefore, the total number of valence electrons in KBr is 1 (from K) + 7 (from Br) = 8 valence electrons.
The outermost electrons are called VALENCE electrons.
In the calculation of valence electron counts using the 18-electron rule, phosphine (PH3) contributes 5 valence electrons. Since each hydrogen atom contributes 1 electron, the total valence electron count for PPh3 (Ph = phenyl group) would be 5 (from phosphorus) + 3x1 (from hydrogen) = 8 electrons.
