al3+ noble gas configuration

So for sodium, we make the substitution of $$\left[ \ce{Ne} \right]$$ for the $$1s^2 2s^2 2p^6$$ part of the configuration. Our tutors rated the difficulty ofWhich ion does not have a noble gas configuration in its gro...as high difficulty. When we write our electron configurations, we utilize the valence orbitals relative to each period to construct it, and write a superscript for the maximum number of electrons in each orbital for each given period. As 3- → -3 charge → addition of 3 electrons → 3 + 5 = 8 valence electrons → noble gas configuration. So for sodium, we make the substitution of $$\left[ \ce{Ne} \right]$$ for the $$1s^2 2s^2 2p^6$$ part of the configuration. Free LibreFest conference on November 4-6! A noble gas configuration of an atom consists of the elemental symbol of the last noble gas prior to that atom, followed by the configuration of the remaining electrons. 4 - Which noble gas has an electron configuration... Ch. Which of the following has a noble gas electron configuration? We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. What are some examples of electron configurations? Based on our data, we think this problem is relevant for Professor Song's class at University of Western Ontario. What is the electron configuration of chromium? Al3+ is losing electrons so you write the electron configuration for the noble gas in the period above, which is neon. 4 - Indicate whether or not each of the following... Ch. Again, the number of valence electrons increases from one to eight across the third period. Add your answer and earn points. The noble gases have the same problem - there is no room for any more electrons in their outer shells. So for example, Cl- is gaining electrons, so you write the electron configuration for argon. They are helium, neon, argon, krypton, xenon, and radon. #cancel(stackrel("Period 1")overbrace(1s^2) stackrel("Period 2")overbrace(2s^2 2p^6))^([Ne]) stackrel("Period 3")overbrace(3s^2 3p^1)#, 9314 views You had a great meal, but cannot put another bite in your mouth because there is no place for it to go. You can view video lessons to learn Electron Configuration. around the world. Its electron configuration is $$1s^2 2s^2 2p^6 3s^1$$. Therefore, we just have: Clutch Prep is not sponsored or endorsed by any college or university. What is the ground state electron configuration of the element germanium? Find an answer to your question Which of the following has a noble gas electron configuration? -3 charge → addition of 3 electrons → 3 + 5 = 8 valence electrons → noble gas configuration, +3 charge  → loss of 3 electrons → 3 - 3 = 0 or 8 valence electrons → noble gas configuration, See all problems in Electron Configuration, video lessons to learn Electron Configuration. Get a better grade with hundreds of hours of expert tutoring videos for your textbook, By registering, I agree to the Terms of Service and Privacy Policy, Concept: The s,p, d, f sublevels and the Periodic Table, Noble gas configuration → must have 8 valence electrons either by gaining or losing electrons, As → Group 5A atom → 5 valence electrons → needs 3 more electrons, As3- → -3 charge → addition of 3 electrons → 3 + 5 = 8 valence electrons → noble gas configuration, Al → Group 3A atom → 3 valence electrons → needs to lose 3 electrons, Al3+ → +3 charge  → loss of 3 electrons → 3 - 3 = 0 or 8 valence electrons → noble gas configuration. All the elements can be represented in this fashion. Or if you have to write it doing noble gas core, it would be (Ne) 3s^2 3p^6. Ch. What is the electron configuration for a sodium ion? How do electron configurations affect properties and trends of a compound? [ "article:topic", "showtoc:no", "noble gas configuration", "license:ccbync" ], 5.19: Hund's Rule and Orbital Filling Diagrams. A noble gas configuration of an atom consists of the elemental symbol of the last noble gas prior to that atom, followed by the configuration of the remaining electrons. How do electron configurations in the same group compare? What is the electron configuration for a nitride ion? Or if you need more Electron Configuration practice, you can also practice Electron Configuration practice problems. Noble gas configuration → must have 8 valence electrons either by gaining or losing electrons. Have questions or comments? Na atom Al3+ ion Mg+ ion Br atom HACKZio is waiting for your help. What scientific concept do you need to know in order to solve this problem? 4 - Which noble gas has an electron configuration... Ch. a) As3- b) Al3+ c) Ga3+ d) Sc3+ FREE Expert Solution. 4 - Which noble gas is isoelectronic with each of the... Ch. They are completely full and cannot handle any more. The basis of all chemical reactions is the tendency of chemical elements to acquire stability. The LibreTexts libraries are Powered by MindTouch® and are supported by the Department of Education Open Textbook Pilot Project, the UC Davis Office of the Provost, the UC Davis Library, the California State University Affordable Learning Solutions Program, and Merlot. Sodium's noble gas configuration becomes $$\left[ \ce{Ne} \right] 3s^1$$. #[Ne] = 1s^2 2s^2 2p^6#. To write the noble gas shorthand configuration, you simply find the previous noble gas, which is neon, and determine which orbitals in the full configuration you've already accounted for by shortening the notation. This provides the basis for a shorthand notation for electron configurations called the noble gas configuration.
