Negative ion. Cl-
generally negatively charged chloride ion. but there are a few species where chlorine has positive charge like ClO3-, ClO4- etc.
forms a covalent bond APEX:They form an ionic compound.
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.
False. Sodium tends to lose an electron to form a positive ion, while chlorine tends to gain an electron to form a negative ion. This opposite transfer of electrons is what allows sodium and chlorine to readily combine and form salt (sodium chloride).
positively
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
When elements first come together they are both electrically neutral. When they get close enough, an electron transfers from the sodium to the chlorine. This makes the a positive sodium ion, Na+, and a negative chlorine ion, Cl-.
A positive ion and a negative ion.
No, sodium and chlorine do not form a covalent bond. They typically form an ionic bond, where sodium loses an electron to form a positive ion and chlorine gains an electron to form a negative ion, resulting in an attraction between the two ions.
Chlorine readily gains an electron to form a chloride ion with a negative charge of -1.
A positive ion is an ion with no negative charges.
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.
Sodium Chloride does not have free electrons normally, Sodium with electron arrangement: 2,8,1 and Chlorine with electron arrangement: 2,8,7 When they react Sodium ionises to 2,8 ( Ne) Chlorine gains the free electron to ionise to 2,8,8 (Ar) Forming Sodium Chloride or Na+CL-
