Chlorine is a yellow-green gas at room temperature. How does a chlorine atom become a chloride ion? A chlorine atom has an atomic number of 17. Chlorine is a chemical element with the symbol Cl and atomic number 17. Ions. Because it has unequal numbers of protons and electrons, it’s now an ion. Essentially, when atoms gain or lose electrons, they become ions. Eg. The covalent radius of a chlorine atom, for example, is half the distance between the nuclei of the atoms in a Cl 2 molecule. Under standard conditions, the element is a yellow-green gas. b. to attain a noble-gas electron configuration. Sodium atoms have 11 electrons. ... (such as chlorine). The sodium atom becomes a positive ion,, and the chlorine atom becomes a negative ion. How to solve: How many electrons will chlorine gain or lose when it forms an ion? 8) In order to become an ion, an atom of chlorine must _____. Now consider the chlorine atom in sodium chloride. Now, let's consider chlorine atom, Cl: 1s 2 2s 2 2p 6 3s 2 3p 5. The size of an atom can be estimated by measuring the distance between adjacent atoms in a covalent compound. For a chlorine atom to become a chloride ion, the chlorine atom must A. gain one electron B. lose one electron C. share an electron D. lose all its electrons which one is it? • Chloride ion is attracted to positively charged electrodes or other positively charged chemical species, but chlorine does … Top Answer. 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. The chloride ion now has eighteen electrons and seventeen protons, so it's become a negative ion. Hang on, “chlorine ion” is not correct. In chemistry an atom of a particular element is said to be reduced when it gains an electron (from another atom). An ion is an atom or a molecule carrying some specific charge due to loss or gain of electrons. Wiki User Answered . Opposite charges attract one another while similar charges repel one another. O C. The atom loses 1 proton, to make a total of 36. 1. chlorine atom has become an anion (AN-ı¯-on), a negatively charged ion. "# 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 … #"An ion is a species with an excess or deficiency of electrons. What kind of ions do a sodium atom and a chlorine atom become when a valence electron is transferred from one to the other. The formula of this compound would therefore be KCl. 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). Chlorine atom is a neutral species and has no charge on it. The ionic form of chlorine is called a chloride ion. Then the atom is called a positive ion. Ca atom loses two electrons and becomes Ca 2+ ion. The neutral chlorine atom becomes the chloride ion. The covalent radii of the main group elements are given in … There is a huge difference between a chlorine atom and a chloride ion. have a great day! 1 2 3. Chlorine, as mentioned above, desperately wants an electron so it can fill its outer electron level. 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. 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). Chlorine The electron configuration of a chlorine atom is $[\mathrm{Ne}] … 01:17. 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. The Chloride Ion.
