Chloride anion has 8 valence electrons.
Chlorine (Cl) has 7 valence electrons, as it is in Group 17 or 7A of the periodic table. This means it has 7 electrons in its outermost energy level.
In an atom of Cl, there are 7 valence electrons. If you look at a Chemistry Reference table (2002 edition) pages 8 and 9, (visit the link below), you can see that underneath Cl there are the numbers 2-8-7. The last number is the number of valence electrons. This is found for any element on the Period table.
The ICl4- ion has 36 valence electrons. Iodine contributes 7 valence electrons and each chlorine atom contributes 7 valence electrons, totaling 36 valence electrons in the ICl4- ion.
The NCl3 molecule, like most other stable molecules, exist because they share electrons in such a way as to close out the valence shell. Therefore, although one usually doesn't say so in regards to molecules, NCl3 has 8 valence electrons.
Ca has 2 valence electrons, and Cl has 7 valence electrons.
Since Be is in the 2nd group, it should have 2 valence electrons and Cl should have 7 (in 7th group), and since there is 2 Cl, then there is 14. Add 14 Cl electrons and 2 Be electrons to get 16 electrons (valence, not total)
Chloride anion has 8 valence electrons.
In the Lewis structure for LiCl, there are 1 valence electron from lithium (Li) and 7 valence electrons from chlorine (Cl) that need to be accommodated. This gives a total of 8 valence electrons in the Lewis structure for LiCl.
Chlorine (Cl) has 7 valence electrons, as it is in Group 17 or 7A of the periodic table. This means it has 7 electrons in its outermost energy level.
Carbon (C) has 4 valence electrons, hydrogen (H) has 1, fluorine (F) has 7, and chlorine (Cl) has 7. Therefore, CHF2Cl has 24 valence electrons in total.
CH2Cl2 has 20 valence electrons. Each carbon contributes 4 valence electrons, each hydrogen contributes 1 valence electron, and each chlorine contributes 7 valence electrons.
Fluorine is the element that has 7 valence electrons.

There are 20 valence electrons in CH2Cl2. C => 4 e-* x 1 (number of C in chemical formula) = 04 v.e-** H => 1 e- x 2 = 02 v.e- Cl => 7 e- x 2 = 14 v.e- CH2Cl2 = 20 v.e- *e- - this means electrons in short form **v.e- - this means valence electrons in short form
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.
