Chlorine has 7 valence electrons in the 3rd electron shell. Chlroine is in the third row of the periodic chart, so its 3rd shell is the valence shell, and it is in the next to last column, 7A, so it has 7 electrons in that 3rd shell.
An atom of chlorine has 7 valence electrons because it is in group 17 of the periodic table.
A chlorine atom has 7 valence electrons, as it is in group 17 of the periodic table. A chloride ion has 8 valence electrons, as it gains an additional electron to achieve a full octet and a stable electron configuration.
I think that because chlorine has 17 electrons in all, and ten of them are filled up on the first two shells, then seven of them should be on the third shell, so seven of them are valance 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
A sodium atom has 1 electron in its valence shell, while a chlorine atom has 7 electrons in its valence shell. When sodium reacts with chlorine to form sodium chloride, the sodium atom loses its 1 electron to achieve a stable octet configuration, while the chlorine atom gains this electron. The resulting sodium chloride molecule has 8 electrons in the valence shell of the chlorine atom.
An atom of chlorine has 7 valence electrons because it is in group 17 of the periodic table.
In every chlorine atom, there are seven valence electrons.
Chlorine has 17 electrons. 7 of its electrons are valence electrons.
A chlorine atom has 7 valence electrons, as it is in group 17 of the periodic table. A chloride ion has 8 valence electrons, as it gains an additional electron to achieve a full octet and a stable electron configuration.
In any atom, the valence electrons are located in the outermost shell. Chlorine has 7 valence electrons.
I think that because chlorine has 17 electrons in all, and ten of them are filled up on the first two shells, then seven of them should be on the third shell, so seven of them are valance electrons.
In the question, it should be either "chlorine atom" or "chloride ion". Chlorine atom has 7 valence electrons. Chloride ion has 8 valence electrons.
7, as does an atom of any halogen (element in column 17 of a wide form periodic table.)
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.
CH3CO-OH (acetic acid) has 10 valence electrons. The carbon atom contributes 4 valence electrons, each hydrogen atom contributes 1 valence electron, and the oxygen atom contributes 6 valence electrons.
Valence electrons are the electrons from the outermost shell of the atom.

One chlorine atom will form an ionic bond with one magnesium atom. The magnesium will donate its two valence electrons to the chlorine atom, filling both of their valence electron shells.
