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.
To determine the number of valence electrons in SiCl3Br, we need to account for the valence electrons of each atom in the molecule. Silicon (Si) has 4 valence electrons, each chlorine (Cl) atom has 7 valence electrons, and bromine (Br) has 7 valence electrons. Therefore, the total is 4 (Si) + 3 × 7 (Cl) + 7 (Br) = 4 + 21 + 7 = 32 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)
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.
Cl2 is the diatomic molecule of chlorine (Cl) . It has 14 valence electrons, 7 in each atom. When chlorine forms a chloride ion, an atom accepts an electron and becomes Cl- (negative ion).
Cl- has 8 valence electrons. This is because chlorine, in its neutral state, has 7 valence electrons (group 17), and the -1 charge of the chloride ion indicates the addition of an extra electron.
2 valence electrons for calcium and 7 for chlorine.
A Cl⁻ anion has gained one electron compared to a neutral chlorine atom. A neutral chlorine atom has 7 valence electrons, with the electron configuration of [Ne] 3s² 3p⁵. Therefore, in the Cl⁻ anion, there are 6 electrons in the 3p subshell, as it now has a total of 8 valence electrons (3s² 3p⁶).
Chloride anion has 8 valence electrons.
CFC-113, or trichlorofluoromethane (CCl3F), has a total of 26 valence electrons. The carbon atom contributes 4 valence electrons, each of the three chlorine atoms contributes 7 valence electrons (totaling 21), and the fluorine atom contributes 7 valence electrons. Thus, the total count is 4 (C) + 21 (3 Cl) + 7 (F) = 32 valence electrons.
Valence electrons are the electrons from the outermost shell of the atom. Number of valence electrons in an atom = the group number of that atom Valence electrons of a moleucle = sum of the valence electrons of all the atoms in that molecule. The molecule HCl has 1 hydrogen (group number =1) and 1 chlorine atom (group number =7). The total number of valence electrons in HCl = 1(1) + 1(7) = 8 Pushpa Padmanabhan Lansing Community College
The atom with seven valence electrons and two more protons than phosphorus is chlorine (Cl). Chlorine has 17 protons and 7 valence electrons, while phosphorus has 15 protons and 5 valence electrons.
if you are asking about ICl4- ion then there are 28 valence electrons and 8 binding ones.total of 36 electrons
