Element 17's valence electron configuration is 3s23p5.
It has two valance electrons. Abbreviated electron configuration. [Ar] 3d^10 4s^2 ( energy wise that would be 4s^2 3d^10 )
Fr is in the 1st period. It removes an electron to get noble gas configuration. Fr+ does not have valence electrons.Francium has 1 electron in its outermost energy level. It donates its outermost electron to stabilize its electron configuration. Francium(I) has no valence electrons.

1s2 2s2 2p6 3s1There are 11 electrons orbiting around the nucleus of Na. The Last one (3s1) is the valance Electron.

The cation sodium. Na + The anion chlorine. Cl - NaCl ----------------sodium chloride Sodium only has the one valance electron to donate to an ionic bond and chlorine can accept only one electron into it's valance shell. Then their octets are complete. So, NaCl2 is not possible as chlorine could not accept an electron not being donated in this invalid compound.
The valance electron configuration is the same in each at ns1 where n = the period number.
Same "fullness" of the valance band.
depending the types of metal or non-metal in periodic table.
The valance electron configuration is the same in each at ns1 where n = the period number.
The valance shell is important in chemical reactions, as it is the valance electrons which are gained/lost during reactions. An atoms valance electron configuration is what largely determines its chemical reactivity.
Valence electron configuration of zinc, abbreviated. [Ar] 4s2 3d10 Zinc's oxidation state is 2, so that 4s2 represents the valance electrons though they are at a lower energy level and the 3d10 gives you the full outer electron configuration.

Element 17's valence electron configuration is 3s23p5.
It has two valance electrons. Abbreviated electron configuration. [Ar] 3d^10 4s^2 ( energy wise that would be 4s^2 3d^10 )
to find the electron dot configuration of an element simply draw dots, symbolizing valance electrons, in a way that they are farthest from each other around the symbol of the element you are using.
