Negative ion. Cl-
Chlorine forms a negative ion.
generally negatively charged chloride ion. but there are a few species where chlorine has positive charge like ClO3-, ClO4- etc.
An anion is a negatively charged ion. Chlorine, because it wants to "steal" or "borrow" an electron to achieve that "magic" inert gas electron configuration will be a negative or anion. The chlorine ion's "extra" electron will give it an overall negative charge. The anion of chlorine is written as Cl- by those who annote it in chemistry.
positively
Sodium is a non-transition metal so it can only form one type of ion, that is Na+ or Na+1. It loses it's only valence electron to a nonmetal so that it can assume a noble gas configuration and be at its most stable state.
Negative (Fl-) All the halogens become negative ions.
Chlorine forms a negative ion.
Chlorine will form a negative ion with a charge of -1 because it gains one electron to complete its octet.
Chlorine would form a negative ion and the other three positive ions.
Non it is neutral
This will produce a negative ion, called an anion. Non-metals such as chlorine form anions. See the link
Fluorine is negative and will produce a negative ion.
generally negatively charged chloride ion. but there are a few species where chlorine has positive charge like ClO3-, ClO4- etc.
A positive ion and a negative ion.
A positive ion and a negative ion.
A positive ion and a negative ion.
Negative 1
None of them. Cl is the symbol for an atom of chlorine. If it were a compound there would be at least one other symbol, and the same applies to a polar molecule. If it were a negative ion it would be Cl- with the negative sign as a superscript. Chlorine doesn't form positive ions in normal circumstances, but it would be Cl+ , again with the charge as a superscript.
