Neutral selenium has 6 valence electrons.
Valence electrons can be found in the s and p orbitals in an atom. The s orbital can hold a maximum of 2 electrons, while the p orbitals can hold a maximum of 6 electrons. This arrangement allows for a maximum of 8 valence electrons in an atom.
Two valence electrons
Argon does not contain valence electrons.
Valence electrons are electrons on the outermost shell/orbitals. Sheilding electrons are inner electrons that block valence electrons from protons causing less attraction.
The valence electrons in main group elements are typically found in the s and p orbitals. Group 1 and 2 elements have valence electrons in s orbitals, while groups 13-18 elements have valence electrons in both s and p orbitals.

Lead has 82 electrons. It also has four valence electrons, two s- electrons and two p- electrons in its orbitals.
three, as follows:the 4s orbital is full with 2 electronsthe 4p orbitals contain only 1 electron (of a possible 6)
A neutral atom of oxygen would have 6 valence electrons.
A neutral atom of fluorine contains 7 valence electrons.
A neutral atom of aluminum has 3 valence electrons.
Neutral selenium has 6 valence electrons.
Valence electrons can be found in the s and p orbitals in an atom. The s orbital can hold a maximum of 2 electrons, while the p orbitals can hold a maximum of 6 electrons. This arrangement allows for a maximum of 8 valence electrons in an atom.
Three degenerate orbitals are needed to contain seven electrons with five of them being paired in o orbitals. These would consist of two orbitals with 2 electrons each and one orbital with 3 electrons.
