Seven.
That is chlorine and it has seven valance electrons.
an element with 2 valence electrons can obtain a stable electron configuration by "kicking out" two electrons to have the same electron config as the noble gas in the previous period
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.
Chlorine's atomic number is 17. Thus, neutral chlorine has 17 protons and 17 electrons. Its total configuration is 1s2 2s2 2p6 3s2 3p5, so its valence configuration is 3s2 3p5.
Silicon has 4 valence electrons. No noble gases will have 4 valence electrons.
With an e- configuration of [Ne] 3s23p5, the atom will be found in Group VII A, meaning that there are 7 valence electrons.
Seven.
The element chlorine has seven electrons in its valence shell.
There are 7 valence electrons in chlorine.
There are 7 valence electrons in a chlorine atom. The atomic number of chlorine is 17, which means it has an electron configuration of 2,8,7. This shows it has 3 shells of electrons, with 7 in the outer level.
yes, chlorine has 7 valence electrons
The valence electrons are the outermost (highest energy) s and p sublevels. There are 5 valence electrons in a phosphorus atom, and it is in period 3, so its valence electron configuration is 3s23p3.

1 additional electron will give chlorine 8 in the valence. You can see in the Periodic table, that Chlorine is next to Argon ( 1 to the left of it) so it needs 1 more electron to have the same configuration as Argon.
