how does a chlorine atom become an ion

1 See answer Answer 5.0 /5 7. calipriester +9 ... 27 minutes ago There are two main isotopes of chlorine. Do you like rain. The atom that took the electron or 2 became a negatively charged ion. d=D. will it become a positively charged cation or a negatively charged anion? Hang on, “chlorine ion” is not correct. 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. Ions. #"An ion is a species with an excess or deficiency of electrons. And because ions that have a negative charge are called anions, it’s now called the: The covalent radius of a chlorine atom, for example, is half the distance between the nuclei of the atoms in a Cl 2 molecule. How to solve: How many electrons will chlorine gain or lose when it forms an ion? When chlorine gains an electron to become a chloride ion with a 21 charge, ... Chlorine The electron configuration of a chlorine atom is $[\mathrm{Ne}] 3 \… 00:43. 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. Chlorine is a naturally occurring element with a symbol Cl and atomic number 17. The atom that has lost an electron becomes a positively charged ion (called a cation), while the atom that picks up the extra electron becomes a negatively charged ion (called an anion). The electronic configuration for the chloride anion is: The process that changes a chlorine atom into a chloride ion is a reaction known as a reduction reaction. The Chloride Ion. 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). Opposite charges attract one another while similar charges repel one another. "# A given atom, say #"chlorine"# or #"sodium"# has a given number of protons, fundamental positively charged NUCLEAR particles, which is given by #Z#, the atomic number.For #Cl#, #Z=17#; for #Na#, #Z=11#.Chlorine atoms tend to gain electrons to form negatively charged ions with 18 electrons (the difference between … Chlorine atoms gain one electron to become a chloride ion (Cl−). The ionic form of chlorine is called a chloride ion. The atom gains 1 electron, to make a total of 18. The sodium atom becomes a positive ion,, and the chlorine atom becomes a negative ion. Chlorine in its free form is very dangerous if you breathe the fumes or come in contact with the gas. 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. When an atom has an unequal number of protons and electrons it is an ion. 8) In order to become an ion, an atom of chlorine must _____. There is a huge difference between a chlorine atom and a chloride ion. 2010-12-11 15:34:00. it gains an electron. chlorine atom has become an anion (AN-ı¯-on), a negatively charged ion. Chloride is an ion of chlorine. have a great day! The size of an atom can be estimated by measuring the distance between adjacent atoms in a covalent compound. 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. Ca atom loses two electrons and becomes Ca 2+ ion. In chemistry an atom of a particular element is said to be reduced when it gains an electron (from another atom). What kind of ions do a sodium atom and a chlorine atom become when a valence electron is transferred from one to the other. Use this information to w. It has a charge of 1 and is written Cl.When an atom of sodium donates its sole valence electron to an atom of chlorine, the result-ing positive and negative charges pull both ions tightly together, forming an ionic bond (Figure 2.4c). • Chloride ion is attracted to positively charged electrodes or other positively charged chemical species, but chlorine does … The neutral chlorine atom has acquired a negative charge by gaining an electron. The second-lightest of the halogens, it appears between fluorine and bromine in the periodic table and its properties are mostly intermediate between them. b. to attain a noble-gas electron configuration. At this point, chlorine has 17 protons (17 positive charges) and 18 electrons (18 negative charges). An ion is an atom or a molecule carrying some specific charge due to loss or gain of electrons. But on the other hand an atom is a neutral species therefore have no charge on them. Essentially, when atoms gain or lose electrons, they become ions. When a chlorine atom gains an electron, its outermost principal energy level achieves an octet. However, after reaction with sodium, we have sodium chloride formed as the sodium atom gives up an electron to chlorine which accepts the electron to form the chloride anion. Ions consisting of only a single atom are termed atomic or monatomic ions, while two or more atoms form molecular ions or polyatomic ions. The atom gains 1 electron, to make a total of 21. Only one more electron is needed to achieve an octet in chlorine’s valence shell. Chlorine, as mentioned above, desperately wants an electron so it can fill its outer electron level. Chlorine is a chemical element with the symbol Cl and atomic number 17. Simultaneously, the chlorine atom, having gained an extra electron, will take on a negative charge and become a chlorine ion. Now, let's consider chlorine atom, Cl: 1s 2 2s 2 2p 6 3s 2 3p 5. Looking at Ions We've talked about ions before. ... (such as chlorine). Ions form salts, not molecules, but they perform many important functions in nutrition. Now consider the chlorine atom in sodium chloride. 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. Asked by Wiki User.
