WebThe first two electrons of lithium enter the 1s orbital. The s-orbital can have a maximum of two electrons. Therefore, the remaining one electron enters the 2s orbital. Therefore, the lithium full electron configuration will be 1s 2 2s 1. Lithium electron configuration Note: The short electron configuration of lithium is [ He] 2s 1. WebNov 7, 2012 · Results and Discussion. As shown in figure 1, Li 2 O 2, crystallizes in a P63/mmc hexagonal space group where the peroxide anions are arranged in an alternating ABAB stacking. There are two distinct Li + sites: one is in the same layer as the peroxide anions and the other one is in between the peroxide layers. The crystal structure of Li 2 …

WebThe energy of the first stationary state (n=1) of Li 2+ is: A 4.41×10 −16J.atom −1 B −4.41×10 −17J.atom −1 C −2.2×10 −15J.atom −1 D 8.82×10 −17J.atom −1 Medium Solution Verified by Toppr Correct option is B) Since IE He +IE Li 2+=(Z He +Z Li 2+)2= 49 ∴IE Li 2+= 49×IE He +=9/4×19.6×10 −18 =4.41×10 −17J/atom WebSolution The correct option is B 30.6 eV Energy required to move an electron from any state to n =∞ is called the binding energy of that state. So, binding energy = 13.6Z2 n2. For, Li2+, Z=3, n=2 (i.e 1st excited state) Therefore, binding energy = 13.632 22 eV binding energy = 13.69 4 eV Hence binding energy = 30.6 eV Suggest Corrections 0 sunset memorial cemetery minot nd
