Are there always 8 valence electrons?
Atoms are unstable unless they have 8 valence electrons. Thus, only the noble gasses are “born” to be stable. All other atoms must gain, lose, or share electrons to be more like a noble gas. Stable atoms tend to have 8 valence electrons, like the noble gasses.

Can you have 12 valence electrons?
The dot diagram shows that sulfur has 12 electrons in its valence shell. Here the sulfur atom has six electron pairs in its valence shell. An atom like phosphorus or sulfur which has more than an octet is said to have expanded its valence shell.

What elements dont have 8 valence electrons?
Hydrogen, beryllium, and boron have too few electrons to form an octet. Hydrogen has only one valence electron and only one place to form a bond with another atom. Beryllium has only two valence atoms, and can form only electron pair bonds in two locations.

What does it mean if an element has 6 valence electrons?
Valence electrons are the electrons in the outermost shell, or energy level, of an atom. For example, oxygen has six valence electrons, two in the 2s subshell and four in the 2p subshell. We can write the configuration of oxygen’s valence electrons as 2s²2p⁴.

What elements can only have 6 valence electrons?
Elements with six valence electrons are the chalcogens (O, S, Se, Te, Po, and Lv). Most of these elements are nonmetals.

What period has 6 valence electrons?
The Group 6A elements have six valence electrons in their highest-energy orbitals (ns2np4). This is only two electrons away from having a full octet of eight electrons, so many of these elements form anions having -2 charges: oxide, O2-; sulfide, S2-, selenide, Se2-, etc.
