What electron could have quantum numbers n 2 l 1 m?
L-1 electron configuration
Why electronic configuration of scandium is 2 8 9 2 not like 2 8 8 3?
Scandium is a transition element, so it has properties quite different. so instead of having 2-8-8-3 it sends 1 electron to the inner L shell and becomes 2-8-9-2
What element has the structure 2 8 3?
Ah, what a delightful question! The element with the electron configuration 2 8 3 is sodium. Just imagine those electrons peacefully arranging themselves around the nucleus, creating a lovely balance in the atom. Sodium is a friendly element that loves to interact with others, bringing joy and stability to chemical reactions.
What ions does not have the same electron configuration as the noble gas neon a o minus 2 b f minus c al plus 3 d s minus 2 e mg plus 2?
D. S-2Electron configuration has to do with the number of electrons, so using a Periodic table, it is easy to find this answer.For example, O-2 has 2 more electrons than usual, so move two spaces to the right, which is neon.For F- , it is the same way. Since it is a minus 1, move one space to the right, which is neon.For Al+3 there are 3 LESS electrons than usual so move back(to the right) 3 spaces, which is neon.For S-2 , the answer to your problem, has the same electron configuration as Argon.For Mg+2 there are 2 less electrons so moving back 2 spaces gives you neon.Remember 'minus' means more electrons so for electron configurations you move forward on the Periodic table for ions with negative charge and backwards if the ion is positive.
What electron could have quantum numbers n 4 l 2 ml -2 ms?
A 4d electron; that is for apex :)
