What are the quantum numbers for the last electron in gold?
5, 2, +1, -1/2 :)
What is the quantum number for the last electron in cobalt?
expected configuration for Cr is 1s2 2s2 2p6 3s2 3p6 4s2 3d4 but in real, it is 1s2 2s2 2p6 3s2 3p6 4s1 3d5 electron from 4s orbital jumps to 3d orbital to get stable configuration. so the last electron comes in 3d orbital as filling of 3d takes place after filling of 4s orbital. Hence,quantum numbers for last electron in Cr is :- n = 3 l = 2 m = +2 s = +1/2
What are the four principal quantum numbers for krypton?
n=4 l=2 ml= -1 ms= +1/2
Why is the electron configuration for copper 1s22s22p63s23p63d104s1 instead of 1s22s22p63s23p63d94s2?
Because a full 4s orbital is more stable than a full 3d and half full 4s. So, the last 3d electron jumps up to the 4s orbital.
Do electrons travel in pairs?
Electrons do not travel in pairs. An atomic or molecular orbital can hold a pair of electrons, which is probably what you're thinking of. The reason for this is that electrons are fermions: two electrons in an atom or molecule cannot have the exact same quantum state. Specifying the orbital uses up 3 of the 4 quantum numbers for describing an electron's quantum state; the last quantum number is the spin angular momentum which can either be +1/2 or -1/2, so two electrons per orbital. After that it's full and no more electrons can go into that orbital. Note that far from "traveling in pairs", fermions really don't like to be even that close to each other. If there are three orbitals at the same energy level, one electron will go into each before they start to "double up".

What quantum number is a whole number?
The first three quantum numbers (principle, angular momentum, magnetic) are all whole numbers. The last quantum number (spin) is either ½ or -½.
Which material can last the longest heat - copper or styrofoam or procelain?
Copper as it had large amout of free electron in it.
What are the quantum numbers for iodine?
Quantum numbers are a set of 4 imaginary numbers which explain the position and spin of electrons in an atom it can not explain an atom as a whole Iodine has 53 electrons so there are 53 sets of quantum numbers for Iodine.The above is correct. Assuming you meant to ask for the quantum numbers for the last electron added to Iodine, that would be n=5, l=1, m=0, s=1/2.
Write the four quantum numbers of last electron in boron atom B?
Boron - 5e-1s^2 2s^2 2p^1n= 2l= 1ml= -1 -> 1ms= -1/2 , 1/2

Because a full 4s orbital is more stable than a full 3d and half full 4s. So, the last 3d electron jumps up to the 4s orbital.
What is a quantum of energy as defined by quantum mechanics?
exact, whole number amount of energy needed to move an electron to a higher energy level
When was the last copper penny?
The last year for copper US pennies was 1982.
When is the last James Bond film?
quantum of solace
What compound is formed when the electron combines with the last electron?
atp
