Lithium atom number of electrons
WebA lithium atom has three electrons. The hrst two of these can have the same sets of quantum numbers as the two electrons of hehum. What should the set of quantum numbers for the third electron be We cannot choose the lowest permitted value for n, which is 1, because C and m would then both be 0. WebElements in the second row of the periodic table place their electrons in the 2n shell as well as the 1n shell. For instance, lithium ( \text {Li} Li) has three electrons: two fill the 1s 1s orbital, and the third is placed in the 2s 2s orbital, giving an electron configuration of 1s^ 2 …
