generally 8, although there are a few special cases involving less.
In a triple bond between two atoms, a total of six valence electrons are involved. Each atom contributes three valence electrons, resulting in three shared pairs of electrons. This type of bond is characterized by one sigma bond and two pi bonds, allowing for a strong and stable connection between the atoms.

Two. One hydrogen atom has one valence electron, so two hydrogen atoms will have two valence electrons :)
The PF6⁻ ion consists of one phosphorus (P) atom and six fluorine (F) atoms. Phosphorus has 5 valence electrons, and each fluorine atom has 7 valence electrons, contributing a total of 42 electrons from the six fluorine atoms. Adding the 5 from phosphorus and accounting for the extra electron due to the negative charge, the total number of valence electrons in PF6⁻ is 48.
Acetylene (C2H2) has 2 valence electrons for each carbon atom and 1 valence electron for the hydrogen atoms. Therefore, acetylene has a total of 10 valence electrons (4 from carbon and 6 from hydrogen).
In a triple bond between two atoms, a total of six valence electrons take part. Two electrons come from each atom to form the sigma bond, and the remaining four electrons form two pi bonds.

A carbon atom has 4 valence electrons. So, for a C6 molecule, there will be a total of 6 carbon atoms, and each carbon atom will contribute 4 valence electrons, giving a total of 24 valence electrons in the C6 molecule.
The number of valence electrons in cyclopentadiene C5H6 is 54. Carbon has 4 valence electrons and hydrogen has 1, giving a total of 30 for carbon atoms and 24 for hydrogen atoms.

6 you apex users!
Xenon pentafluoride (XeF5) has a total of 8 valence electrons. Xenon (Xe) contributes 8 valence electrons, while each fluorine (F) atom contributes 7 valence electrons. The 5 fluorine atoms in XeF5 contribute a total of 35 valence electrons.
In a triple bond, a total of six electrons are shared between two atoms. Each atom contributes one electron for a sigma bond, and two atoms contribute two electrons each for two pi bonds.
The PF6⁻ ion consists of one phosphorus (P) atom and six fluorine (F) atoms. Phosphorus has 5 valence electrons, and each fluorine atom has 7 valence electrons, contributing a total of 42 electrons from the six fluorine atoms. Adding the 5 from phosphorus and accounting for the extra electron due to the negative charge, the total number of valence electrons in PF6⁻ is 48.
The answer is not 6 as said here before! The number of valence electrons in O2 (oxygen molecule) is: 12 valence electrons. 6 of them from each oxygen (O) atom. 4 valence electrons make up the double bond between the two oxygen atoms, and the remaining 8 valence electrons form lone pairs (non-bonding pairs) on the oxygen atoms, 2 lone pairs on each. I hope there is some help in this.
