Want this question answered?
Helium has 2 valence electrons. All other noble gases have 8 valence electrons.
The first energy level has a maximum of two valence electrons. The second and third energy levels have a maximum of 8 valence electrons.
Bismuth is in group 15 and has 5 valence electrons
Helium only needs 2 valence electrons to have a filled outermost energy level.
6 valence electrons
The number of valence electrons depends on the element and it could have 1 to 8 valence 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.
3
Oxygen has six valence electrons.
Chlorine has 7 valence electrons.
the number of electrons in a valence shell is 8
There are 3 valence electrons in the highest energy level of Nitrogen. Nitrogen has a total of 5 valence electrons.
Helium has 2 valence electrons. All other noble gases have 8 valence electrons.
The first energy level has a maximum of two valence electrons. The second and third energy levels have a maximum of 8 valence electrons.
Bismuth is in group 15 and has 5 valence electrons
Except for elements 1 and 2, all elements are stable with how many electrons in their outermost (valence) level?
