Chlorine is a yellow-green gas at room temperature. See Answer. 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. The atom that took the electron or 2 became a negatively charged ion. Under standard conditions, the element is a yellow-green gas. Hang on, “chlorine ion” is not correct. Chlorine does not exist as an ion, perhaps you mean chloride ion. 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). O D. When it does, the sodium atom becomes a sodium ion with a charge of positive one (+1). When an atom has an unequal number of protons and electrons it is an ion. • Chlorine is more chemically reactive than chloride because it is more unstable. When an atom loses an electron or 2, it has more protons than electrons, and so more positive charges than negative. Metal atoms lose electrons becoming positively charged ions. How to solve: How many electrons will chlorine gain or lose when it forms an ion? will it become a positively charged cation or a negatively charged anion? An ion cannot remain in a free state, and has to combine with another [2] Na atom loses 1 electron and becomes Na+ ion. The process that changes a chlorine atom into a chloride ion is a reaction known as a reduction reaction. Top Answer. Answer to Calculate the charge for a chlorine (CI) ion if a chlorine atom gains an electron to become an ion. 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. So chlorine becomes an ion with a single negative charge. Potassium forms ions with a positive charge. Ions form salts, not molecules, but they perform many important functions in nutrition. Chlorine, as mentioned above, desperately wants an electron so it can fill its outer electron level. Sodium atoms have 11 electrons. Only one more electron is needed to achieve an octet in chlorine’s valence shell. Chloride is an ion of chlorine. Looking at Ions We've talked about ions before. The chloride ion now has eighteen electrons and seventeen protons, so it's become a negative ion. Eg. A compound is formed when potassium reacts with chlorine, which forms ions with a negative charge. Ca atom loses two electrons and becomes Ca 2+ ion. The sodium atom becomes a positive ion,, and the chlorine atom becomes a negative ion. Simultaneously, the chlorine atom, having gained an extra electron, will take on a negative charge and become a chlorine ion. 75% of chlorine atoms have a mass number of 35, while 25% have a mass number of 37. Chlorine atom is a neutral species and has no charge on it. Of the following atoms, ... How many single covalent bonds must a chlorine atom form to have a complete octet in its valence shell? The formula of this compound would therefore be KCl. 17 35.45 O A. • Chloride has achieved the Argon electron configuration, therefore, stable than the chlorine atom. #"An ion is a species with an excess or deficiency of electrons. When a chlorine atom gains an electron, its outermost principal energy level achieves an octet. Use this information to w. 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 covalent radii of the main group elements are given in … O B. Correct answer to the question How does an atom of chlorine-37 become a chloride ion with a -1 charge? How many electrons does Li atom lose to become an ion? Opposite charges attract one another while similar charges repel one another. This electron is transferred to a chlorine atom to form a chloride ion. The ionic form of chlorine is called a chloride ion. Chlorine in its free form is very dangerous if you breathe the fumes or come in contact with the gas. 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. The atomic number of an element, also called a proton number, tells you the number of protons or positive particles in an atom.A normal atom has a neutral charge with equal numbers of positive and negative particles. How does an atom become a positively charged ion? 8) In order to become an ion, an atom of chlorine must _____. 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). 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. … The Chloride Ion. ... (such as chlorine). An ion is an atom or a molecule carrying some specific charge due to loss or gain of electrons. a. to become ions and attract each other. An atom has an equal number of protons (+ charged) and electrons (- charged). Chlorine undergoes reduction when it forms the chloride ion (Cl-). Chlorine atoms gain one electron to become a chloride ion (Cl−). Now consider the chlorine atom in sodium chloride. 1 See answer Answer 5.0 /5 7. calipriester +9 ... 27 minutes ago There are two main isotopes of chlorine. 1.

An atom that has more or fewer electrons in orbit than protons in its nucleus is called an ion.Once the electron from its valence shell has been transferred, the sodium atom will be missing an electron; it therefore will have a positive charge and become a sodium ion. Then the atom is called a positive ion. An ion is an atom which has an electrical charge, beacause it has either lost some of the electrons or received extra electrons (electrons are negatively charged). The neutral chlorine atom has acquired a negative charge by gaining an electron. The neutral chlorine atom becomes the chloride ion. Chlorine is a naturally occurring element with a symbol Cl and atomic number 17. What kind of ions do a sodium atom and a chlorine atom become when a valence electron is transferred from one to the other. A chlorine atom has an atomic number of 17. Wiki User Answered . how many electrons does chlorine need to gain to become an ion? b. to attain a noble-gas electron configuration. 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. How does a chlorine atom become a chloride ion? Ions with a negative charge due to the gain of electrons are called anions. And because ions that have a negative charge are called anions, it’s now called the: 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. Essentially, when atoms gain or lose electrons, they become ions. 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. There is a huge difference between a chlorine atom and a chloride ion. chlorine atom has become an anion (AN-ı¯-on), a negatively charged ion. have a great day! 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 I'm thinking it's either B or D but im not too sure.
