which electronic configuration is most stable

Select one: a. the strontium ion b. the barium ion c. the xenon ion d. the krypton ion e. the calcium ion . Remember that main group elements typically form ions that are most like their nearest noble gas. Half filled and completely filled orbitals are more stable than any other configuration since they are more symmetrical and energy exchange Occurs readily. ... ground state electron configurations. We’re being asked to determine the electron configuration of the most stable ions formed by Al, Ba, Se, and I.. To answer this, we need to do the following steps: Step 1: Determine the number of electrons in the neutral element. 1s2 2s2 2 P6 C. 1s2 2s 1 D. 1s2 2s2 2p3 E. 1s2 2s2 2p6 3s2 3d10 How Many Moles Of Hydrogen Are Needed To Make 32 Moles Of Ammonia (NH3)? It would be Na 7- and Cl 7+, which is much less stable than Na + and Cl -. 2. 8) What is the most likely charge on an ion formed by an element with a valence electron configuration of n? A full valence shell is the most stable electron configuration. There are just a few rules/definitions to keep in mind in order to 'build up' atomic configurations properly. Aufbau principle the principle that states that an atom's electron configuration is developed by progressively adding electrons that assume their most stable conditions in electron orbitals with respect to the nucleus and the other electrons If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices. An atom may give, take, or share electrons with another atom to achieve a … If it's a stable negative ion, it'll be either F- or O2-. • Electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 Caesium belongs to group 1. Rb after losing 1 electron forms and attains most stable Kr configuration. We can base our prediction on the observation that noble gas configurations are the most stable. Everything is based on energy. Find an answer to your question “Which electron configuration of the 4f energy sublevel is most stable? What is a Stable Electron Configuration? 1s2 2s2 2p5 B. • Copper ions usually exists in either the +1 or +2 forms. Atoms are more stable when they have no charge, or a small charge. The +2, or cupric, ion is more stable than the +1 cuprous ion. However, their charges would be much higher. Performance & security by Cloudflare, Please complete the security check to access. atomic number - symbol - electron configuration. three everyday things that exist or occur because of science. In other words, the valence shell with ns2 np6 electron configuration. So 4f^7& 4f^14 are more stable Nature always is most stable in the lowest energy configurations. A) 1 2 2 B) 1 2 2 C) 1 2 D) 1 2 2 E) 1 2 2 7) What is the most likely charge on an ion formed by an element with a valence electron configuration of n n? So all of these are main group Um, uh, elements and their most stable ions. What minimum mass of H2SO4 would you need? The elements that have fully filled orbitals are most stable, since they do not need to gain or lose electrons. Your IP: 46.105.58.56 Which electron configuration of the 4f energy sublevel is the most stable A. Explain why materials with metallic lattice structures can be used to make wires and connections that conduct electricity in electrical circuits. A. If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware. The energy of atomic orbitals increases as the principal quantum number, n, increases. The electron configuration of outer sublevels that are most stable is 4d up to the 5.5s up to the 1st The most stable form of each of the elements will be the configuration that results in a noble gas configuration. The electron configuration of the 4f energy sublevel is the most stable is 4f to the 14th power. Please enable Cookies and reload the page. Under which circumstances are kp and kc equal for the reaction aa (g) + bb (g) ⇌cc (g) + dd (g) ? You may need to download version 2.0 now from the Chrome Web Store. 4f^7 B. Moreover, the most stable electron configuration possesses a full state of energy. It's most stable ion is Cs+ Electronic configuration = 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10 5s2 5p6 Strontium belongs to group 2.
