Chlorine is number 17 in the Periodic Table, so using the electron shell arrangement,
2:8:7:
It has 7 electrons in its valance shell so its charge becomes Cl7+ when these 7 electrons are 'donated' (= lost to, as reductant) to oxygen (only in oxyacid or salt perchlorate).
Other valence values are +5, +3 and +1 in oxyacids: chlorate, chlorite and hypochlorite, respectively.
A chlorine atom has seven valence electrons.
Seven
There are 7 valence electrons in chlorine atom and 8 valence electrons in chloride ion.
Chlorine has seven (7) valence electrons and seventeen (17) electrons total in its ground state (not an ion or isotope).
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.
A chloride ion has 18 electrons, giving it a valence of -1.
Iodine atom has 7 valence electrons, whereas Iodide ion has 8 valence electrons.
There are 7 valence electrons in chlorine atom and 8 valence electrons in chloride ion.
Chlorine has 7 valence electrons. A chloride ion has 8.
In the question, it should be either "chlorine atom" or "chloride ion". Chlorine atom has 7 valence electrons. Chloride ion has 8 valence electrons.
The hydrogen ion H+ is without electrons.
It has 7 valence electrons.
Chlorine has seven (7) valence electrons and seventeen (17) electrons total in its ground state (not an ion or isotope).
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.
A chlorine ion is monatomic ― it is just Cl-.
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).
A chloride ion has 18 electrons, giving it a valence of -1.
Iodine atom has 7 valence electrons, whereas Iodide ion has 8 valence electrons.
The valence of a monoatomic chlorine ion is 1 and its charge is -1.
