Elements across a series have the same number of atomic energy levels. An elemental series is better known as a period.
atomic orbitals
Electron shells
Elements in the same period have the same number of electron shells, moving across a period (progressing group to group), elements gain electrons and protons and become less metallic. This arrangement reflects the periodic recurrence of similar properties as the atomic number increases.
All elements in the same group have the same number of valence electrons.
the period
Why not?If two atoms have the same number of protons, they're the same element. Therefore, unless they're electrically charged, they must have the same number of electrons as well. So the number of electrons in two different elements must be different if the atoms are electrically neutral.
Assuming that series is used the same way as group in the periodic table, elements in the same series have the same number of valence electrons.
They don't have the same number. that's what makes thme all different
shells
In a series circuit, current will remain the same through all elements, and the voltage drop across elements will vary. So the answer is: it doesn't.

Electron shells
The difference between a series and parallel circuit is that a series circuit is connected in such a way that the same current intensity flows through the elements while a parallel circuit is connected in such a way that the same potential appears across their terminals.
The elements in a group do not have the same number of shells, however, the elements in a horizontal row do have the same number of shells.
No, none of two elements in any group have the same number of neutrons. But there are such elements across a period, and they are known as isotones. Some examples are; carbon-12 and nitrogen-13 oxygen-18 and fluorine-19 phosphorus-31 and sulfur-32
All elements in the same group have the same number of valence electrons.
Elements have the same number of protons in each atomic nucleus.
