What is the electron configuration for a chloride ion?
2015年12月31日 · 1"s"^2 2"s"^2 2"p"^6 3"s"^2 3"p"^6 OR "[Ne]" 3"s"^2 3"p"^6 The electron configuration of a chlorine atom ("Cl") is as follows: 1"s"^2 2"s"^2 2"p"^6 3"s"^2 3"p"^5 But a chlorine ion ("Cl"^-) has acquired a "(1)-" charge as a result of gaining 1 electron. Thus, its electron configuration is: 1"s"^2 2"s"^2 2"p"^6 3"s"^2 3"p"^6 This may also be expressed as: …
Electrostatic force between sodium ion and a chloride ion
2011年7月5日 · In summary, the conversation discusses the calculation of the electrostatic force between a sodium ion and a chloride ion in solid sodium chloride. The ions are separated by 0.28 nm and the formula used is F = k(q1*q2)/r^2, where q1 and q2 represent the charge of an electron. The answer is obtained by multiplying k by (1.602 * 10^-19)^2.
What kind of ions co-precipitate with chloride? - Physics Forums
2013年11月11日 · In addition to NH4Cl, another possible ion that may co-precipitate with chloride is Fe3+. This can occur when iron(III) chloride (FeCl3) is present in the solution, which can form a precipitate with silver chloride. This can happen if the unknown chloride salt contains iron as an impurity or if iron is present in the solution from other sources.
How do chloride ions form? - Socratic
2016年6月21日 · A chloride ion forms when a chlorine atom gains an electron. This fills the chlorine atom's outer shell, making it electronically stable. It also gives it a single negative charge (-1) due to the extra negatively charged electron.
How many electrons are in the outermost energy level of a …
2017年1月18日 · 8 electrons. 8 valance electrons are a stable structure that allows Chlorine to achieve the same structures as Argon. The sodium ion in salt has a charge of +1. This is because the electron density of the single valance electron of sodium has been taken for the most part by Chlorine. This give Chlorine 8 electrons.
How does a chloride ion differ from a chlorine atom? - Socratic
2016年3月17日 · 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. There is a huge difference between a chlorine atom and a chloride ion. Chlorine atom is a neutral species and has no charge on it. A chlorine atom has an atomic number of 17. It's …
What is chloride's charge? - Socratic
2016年3月14日 · The chloride ion has a SINGLE, NEGATIVE CHARGE. Cl^- has 8 valence electrons. Since the neutral halogen atom has 7 valence electrons, chloride (and fluoride, and bromide, and iodide) bears a FORMAL, NEGATIVE CHARGE. The chorine molecule, Cl-Cl, is NEUTRAL and ZEROVALENT, each chlorine atom has an oxidation state of 0.
Why are chlorine anions larger than chlorine atoms? | Socratic
2018年6月22日 · Due to the difference in the number of electrons. Chlorine has a proton number of 17. By writing out the subshell notation, we know that chlorine atom has 7 electrons in the outermost shell. Chlorine anion, or chloride ion, on the other hand, since it has accepted 1 electron to achieve stable octet arrangement, it has 8 electrons in the outermost shell. The …
Why are chlorides used in flame test? - Socratic
2016年6月21日 · There are two reasons why chlorides are used in flame tests. > 1. Metal chlorides are usually more volatile than other salts. More of the salt will be converted to vapour in the flame and therefore give a brighter colour. 2. Chlorine atoms do not emit energy in the visible region. In the flame test, electrons in both the metal atoms and the chlorine atoms are excited …
How do I calculate the number of chloride ions in a solution?
2017年3月6日 · Here's how you can do that. Your strategy here will be to use the molarity and volume of the solutions to figure out how many moles of salt were dissolved to make the solution. Once you know that, you can use the chemical formula of the salt to figure out how many moles of chloride anions, "Cl"^(-), will be produced in each solution. I'll show you how to solve points A) …
