From the second s orbital: Li(1s2, 2s1) --> Li+(1s2, 2s0) + 1e-
The valence electron in a lithium atom is in orbital 2s. To form a lithium cation, this electron is transferred to some more electronegative atom.
An electron is lost from the 2s orbital
A neutral atom of lithium has an electron configuration of 2,1. This means it has 1 electron in its outer shell.
1s
An atom of yttrium (Y) has an electron configuration of 1s2,2s2,2p6,3s2,3p6,4s2,3d1, so it has one unpaired electron in the 'd' orbital.
The valence electron in a lithium atom is in orbital 2s. To form a lithium cation, this electron is transferred to some more electronegative atom.
An electron is lost from the 2s orbital
Lithium atoms contain one unpaired electron. Two of the three total electrons in a lithium atom are paired in its lowest energy s orbital, which can contain only two.
The charge if a fluorine atom were attract an extra electron from lithium the lithium atom would be positive. -APEX
The lithium atom lose an electron.
ok so you'll notice that lithium is on the second row of the periodic table, this means that its the next orbital hydrogen = 1s1 orbital helium = 2s1 orbital lithium = 2s1, 1s2 orbital removing the outter electron from lithium means that lithium has lost a minus charge and therefore must have a plus charge, this is called a cation. removing the electron also means now that there are no electrons in the s2 level do lithium is left with a 2s1 orbital, this is a very stable configuration and lithium wont loose any more electrons so your lithium ion will be nucleus with 3 protons 4 neutrons and 2 electrons with a plus charge to represent the loss of an electron
