When an atom has an unequal number of protons and electrons it is an ion. Asked by Wiki User. chlorine atom has become an anion (AN-ı¯-on), a negatively charged ion. a. to become ions and attract each other. What kind of ions do a sodium atom and a chlorine atom become when a valence electron is transferred from one to the other. Na atom loses 1 electron and becomes Na+ ion. Under standard conditions, the element is a yellow-green gas. 2010-12-11 15:34:00. it gains an electron. d=D. ... (such as chlorine). When an electric field is applied, the sets of ions move in opposite directions, and since they are much more massive than electrons, the conductivity produced is markedly inferior to that in metals. An ion cannot remain in a free state, and has to combine with another Because the sodium ion has a positive charge, and the chlorine ion has a negative charge, they are attracted to each other, and form an ionic bond. Then the atom is called a positive ion. Ions with a negative charge due to the gain of electrons are called anions. Cl + e —-> Cl- To become the negatively charged chloride ion, the neutral chlorine atom needs to gain an electron from a reducing substance like sodium metal. The ions attach themselves to groups of water molecules. b. to attain a noble-gas electron configuration. • Chloride ion is attracted to positively charged electrodes or other positively charged chemical species, but chlorine does … This makes Chlorine atoms prone to accepting a loose electron to complete its outer shell and therefore form the highly stable Chloride ion, Cl- as shown to the right. have a great day! Chlorine does not exist as an ion, perhaps you mean chloride ion. Of the following atoms, ... How many single covalent bonds must a chlorine atom form to have a complete octet in its valence shell? Metal atoms lose electrons becoming positively charged ions. How many electrons does Li atom lose to become an ion? 1. • Chlorine is more chemically reactive than chloride because it is more unstable. • Chloride has achieved the Argon electron configuration, therefore, stable than the chlorine atom. Chlorine undergoes reduction when it forms the chloride ion (Cl-). Now consider the chlorine atom in sodium chloride. The formula of this compound would therefore be KCl. Reduction is the direct opposite of a reaction called oxidation where an atom loses or gives up an electron and is thus said to be oxidized. Answer to Calculate the charge for a chlorine (CI) ion if a chlorine atom gains an electron to become an ion. The Chloride Ion. The sodium atom becomes a positive ion,, and the chlorine atom becomes a negative ion. Hang on, “chlorine ion” is not correct. #"An ion is a species with an excess or deficiency of electrons. The covalent radius of a chlorine atom, for example, is half the distance between the nuclei of the atoms in a Cl 2 molecule. Expert Answer 100% (2 ratings) Every atom wants to complete its octet i.e there must be eight electrons in its outermost shell. Now it's time to get down to basics. How to solve: How many electrons will chlorine gain or lose when it forms an ion? When a chlorine atom gains an electron, its outermost principal energy level achieves an octet. Chlorine atoms gain one electron to become a chloride ion (Cl−). Looking at Ions We've talked about ions before. Chlorine is a naturally occurring element with a symbol Cl and atomic number 17. Or, it can gain electrons and become negatively charged (the number of electrons would be more than the number of protons giving it an overall negative charge). how many electrons does chlorine need to gain to become an ion? [2] The atom gains 1 electron, to make a total of 18. Chlorine The electron configuration of a chlorine atom is $[\mathrm{Ne}] … 01:17.
