The valence ring can hold up to 8 electrons.
Selenium has 6 valence electrons. It belongs to group 16 of the periodic table, so it has 6 electrons in its outermost energy level.
Bismuth is in group 15 and has 5 valence electrons
Helium has 2 valence electrons. All other noble gases have 8 valence electrons.
Strontium has 2 valence electrons. It is in group 2 of the periodic table, which means it has 2 electrons in its outermost energy level.
The number of valence electrons depends on the element and it could have 1 to 8 valence electrons.
The maximum number of electrons in an energy level (and I assume you mean energy shell- with a principal quantum number) is 2n2 where n is the princiapl quantum number This gives the numebr per level of 2, 8, 18, 32, 50
The valence ring can hold up to 8 electrons.
an atom has different energy orbitals: s, p, d, and f. each orbital can hold two electrons. the outside energy or highest energy levels of electrons is called the valence shell or valence electrons. for an atom to be stable it wants the electron configuration for the valence shell to be "s2, p6." to answer your question the outer level of an atom can hold 8 electrons. it is called the valence shell.
Helium has 2 valence electrons.
The outermost energy level of an atom is known as the valence shell. In general, the valence shell can hold up to 8 electrons. However, the number of electrons that actually fill the valence shell can vary depending on the element and its position in the periodic table.
Boron has 3 valence electrons, gold has 1 valence electron, krypton has 8 valence electrons, and calcium has 2 valence electrons. Valence electrons are the electrons in the outermost energy level of an atom.
Selenium has 6 valence electrons. It belongs to group 16 of the periodic table, so it has 6 electrons in its outermost energy level.
