Those in group VI such as O, S, Se, Te, Po Lv.
Helium atoms only need 2 valence electrons to have a filled outermost energy level because helium is in the first period of the periodic table and its outermost energy level can only hold a maximum of 2 electrons.
Helium only needs two electrons to have a filled outermost energy level.
The valence electrons are the outermost electrons. In an atom, its lower energy levels have been filled and are therefore stable. But, except for the noble gases, the valence energy level is not filled, and therefore not stable. So atoms must undergo chemical reactions in order to fill their valence shells and become stable. They can do this by sharing electrons, transferring electrons, or by forming a sea of electrons shared by all the atoms.
Valence electrons, which are the electrons in the outermost energy level of an atom, are available to form bonds with other atoms. These electrons are involved in the formation of chemical bonds.
The electrons in the outermost energy level of an atom are called valence electrons. These electrons are involved in forming chemical bonds with other atoms to achieve a stable configuration.

Helium only needs two electrons to have a filled outermost energy level.
valence electrons
Outer energy level electrons, or valence electron.
The valence electrons are the outermost electrons. In an atom, its lower energy levels have been filled and are therefore stable. But, except for the noble gases, the valence energy level is not filled, and therefore not stable. So atoms must undergo chemical reactions in order to fill their valence shells and become stable. They can do this by sharing electrons, transferring electrons, or by forming a sea of electrons shared by all the atoms.
Electrons in the outermost energy level (valence electrons) have the highest energy level. These electrons are involved in the atom's chemical reactions and bonding with other atoms.
valence electrons are the electrons found in the outermost energy level of bohr diagram for an element.
An atom's charge changes when it gains or loses electrons. Atoms naturally tend to lose or gain electrons to level out at eight valence electrons (valence electrons are electrons in the outermost energy level), so the only atoms that keep their charge are ions with eight valence electrons or the Noble Gases, atoms on the far right of the periodic table that have eigth valence electrons and a nuetral charge.
Valence electrons, which are the electrons in the outermost energy level of an atom, are available to form bonds with other atoms. These electrons are involved in the formation of chemical bonds.
They share their valence electrons
Helium and neon will have their outer energy level filled with two electrons. Helium has 2 electrons in its only energy level, while neon has 8 electrons in its second energy level.
