Chlorine has one of the highest electronegativity values of any of the elements which means that its electrons are held very tightly to the nucleus. It could be the ions in the air affecting your moods. 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 … But on the other hand an atom is a neutral species therefore have no charge on them. #"An ion is a species with an excess or deficiency of electrons. Ions can be created by chemical reactions. Ions. Ca atom loses two electrons and becomes Ca 2+ ion. The ions attach themselves to groups of water molecules. How does an atom of chlorine-37 become a chloride ion with a - 1 charge? Sodium atoms have 11 electrons. 17 35.45 o a. the atom gains 1 electron, to make a total of 21. o b. the atom gains 1 electron, to make a total of 18. o c. the atom loses - e-eduanswers.com Eg. 1. 1 2 3. 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. Chlorine is a chemical element with the symbol Cl and atomic number 17. The second-lightest of the halogens, it appears between fluorine and bromine in the periodic table and its properties are mostly intermediate between them. The atom gains 1 electron, to make a total of 18. When it does, the sodium atom becomes a sodium ion with a charge of positive one (+1). Because it has unequal numbers of protons and electrons, it’s now an ion. So chlorine becomes an ion with a single negative charge. chlorine atom has become an anion (AN-ı¯-on), a negatively charged ion. How does a chlorine atom become a chloride ion? Do you like rain. O C. The atom loses 1 proton, to make a total of 36. In the case of physical ionization in a fluid (gas or liquid), "ion pairs" are created by spontaneous molecule collisions, where each generated pair consists of a free electron and a positive ion. Chlorine does not exist as an ion, perhaps you mean chloride ion. The covalent radius of a chlorine atom, for example, is half the distance between the nuclei of the atoms in a Cl 2 molecule. The sodium ion Na + is a sodium atom less one electron; the chlorine ion Cl − is a chlorine atom with one electron more than normal. An ion cannot remain in a free state, and has to combine with another O B. Now, let's consider chlorine atom, Cl: 1s 2 2s 2 2p 6 3s 2 3p 5. A chlorine ion contains 17 protons, ... Atom: An atom is the smalled stable structure of matter. Chlorine atom is a neutral species and has no charge on it. When an atom loses an electron or 2, it has more protons than electrons, and so more positive charges than negative. Essentially, when atoms gain or lose electrons, they become ions. 1 See answer Answer 5.0 /5 7. calipriester +9 ... 27 minutes ago There are two main isotopes of chlorine. O D. The Chloride Ion. The neutral chlorine atom has acquired a negative charge by gaining an electron. Ions with a negative charge due to the gain of electrons are called anions. Chlorine undergoes reduction when it forms the chloride ion (Cl-). • Chlorine is more chemically reactive than chloride because it is more unstable.
