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 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 :)
What is subsets and proper subsets?
A set "A" is said to be a subset of "B" if all elements of set "A" are also elements of set "B".Set "A" is said to be a proper subset of set "B" if: * A is a subset of B, and * A is not identical to B In other words, set "B" would have at least one element that is not an element of set "A". Examples: {1, 2} is a subset of {1, 2}. It is not a proper subset. {1, 3} is a subset of {1, 2, 3}. It is also a proper subset.
What is the Electron configuration for 12M?
There is no element such as 12M. Assuming that you mean 12Mg, the electron configuration is 2, 8, 2.
Which element has 1s 2 2s 2 2p 6 3s 1 as its electron configuration?
Sodium.
What is the correct electron configuration for the element Zn?
The atomic number of zinc is 30. Its abbreviated electron configuration is [Ar]4s23d10 The full electron configuration is 1s22s22p63s23p64s23d10 (configurations for the atom in its ground state. Ions and excited atoms have different configurations).
Which is the electron configuration of a transition element for the Bohr orbits?
2-2
What element is Ar 4s3d7?
Zinc has this electron configuration.
What is the valence electron configuration of each element in group 1?
All elements in group 1 have 1 valence electron.
What is the electron configuration for an element in group 2,period 3?
hlkasnh iwhg
How does an element in group 2 attain a stable electron configuration?
It loses 2 electrons and becomes a +2 ion.
Write the electron configuration for this element CI?
[Ne] 3s2 3p5 or 2, 8, 7
What is the electron configuration for the element Al?
Long-hand version: 1s^2 2s^2 2p^6 3s^2 3p^1 Short-hand version: [Ne] 3s^2 3p^1 Note: The "^" symbol means the the following number is in the form of a superscript.
What is the abbreviated electron configuration for Lu atom?
the condensed electron configuration for Lu is [Xe] 6s^2 4f^14 5d^1
What is the element with an electron configuration of 1s22s22p63s1?
With it being a dipositive ion, the original element has lost 2 electrons. Making the configuration 1s2 2s2 2p6 3s2 2p4. That Configuration is Sulfur.
