The valency of an atom can be variable in different compounds or in chemical reactions due to different bonding mechanisms. (a) Zinc (b) Iodine (c) Silicon A valence electron is an electron in the outer shell of an atom that is able to participate in bonding. 1 decade ago. Conclusion. Thanks SO much! a. Zinc b. Iodine. How many valence electrons does nitrogen have? Question: How many valence electrons (electrons in the outer energy level) does oxygen have? A COVID-19 Prophecy: Did Nostradamus Have a Prediction About This Apocalyptic Year? d. Iron 53 total electrons - 7 valence electrons = 46 inner shell electrons. This tutorial discusses how many valence electrons there are in carbon. NOAA Hurricane Forecast Maps Are Often Misinterpreted — Here's How to Read Them. lollipop. Helium. Check out a sample textbook solution. Since Iodine (I) is below Period 3 on the periodic table it can hold more than 8 electrons. Atoms with full shells are stable and are essentially inert. Iodine is below Period Two on the periodic table so it can have an expanded octet (hold more than eight valence electrons). That means it can hold more than eight valence electrons. While iodine has 53 electrons, all but seven are in the inner shells of the iodine … A valence electron is an electron in the outer shell of an atom that is able to participate in bonding. This may seem a bit confusing when one looks at the periodic table, since chlorine is the seventh element in its row, but iodine is the seventeenth. 7 years ago. I'm trying to figure out if I should ignore the d-block.....Would Iodine have 7 valence electrons? Choose the reaction that would not lead to the production of hydrogen gas. Iodine has seven valence electrons. PLEASE HELP ASAP!! These elements are fluorine (F), chlorine (Cl), bromine (Br), Iodine (I), astatine (At), and Tennessine (Ts). Add your answer and earn points. 17. shy5167 shy5167 Answer: wish i could help\ Explanation: New questions in Chemistry. 2 0. What Are Eka Boron Eka Aluminium And Eka Silicon, Difference Between Small And Large Scale Industries, How To Calculate The Equivalent Weight Of Na2co3. While iodine has 53 electrons, all but seven are in the inner shells of the iodine atom. That means Iodine can have an expanded octet--can have more than 8 valence electrons--so we really need to look at the formal charges here to see if this is the most likely structure for IO3-. Your email address will not be published. When sunlight falls on such surface, free electrons getc vibrated and reflect light. 8. c. What is the formula of the compound this element would form with potassium? A valence electron is an electron in the outer shell of an atom that is able to participate in bonding. Log in. Keeping this in consideration, how many valence electrons does IBr2 have? The atomic number of fluorine is 9, and its electronic configuration is [He] 2s2 2p5. = 56), what compound is formed? A fun periodic table. Iodine having valence electrons in the 4th energy level, will also have access to the 4d sublevel, thus allowing for more than 8 electrons. Also note that you should put the ICl4- Lewis structure in brackets with as 1- on the outside to show that it is an ion with a negative one charge. In the Lewis structure for ICl4- the Iodine atom has 12 valence electrons. Like iodine, the other atoms in the halogen family also have seven valence electrons. When more than one atom bonds with others, a molecule is formed. check_circle Expert Answer. In the Lewis structure for IF5 you'll need to put a total of 12 valence electrons on the Iodine atom in order to draw the Lewis structure. A valence electron is an electron in the outer shell of an atom that is able to participate in bonding. shadowblackhear604 shadowblackhear604 05/22/2019 Chemistry High School +5 pts. 7 Answers.
