An electron is lost from the 2s 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.
From the second s orbital: Li(1s2, 2s1) --> Li+(1s2, 2s0) + 1e-

Lithium donates an electron to fluorine, forming lithium cations and fluorine anions that attract each other via ionic bonds. This results in the formation of lithium fluoride, a stable compound that satisfies the octet rule for both lithium and fluorine.
Ionization energy represents the energy required to remove electrons from an atom. The first and second ionization energies are relatively small because the lectrons must be removed from the 2s orbital. For the third ionization energy the electron must be removed from the 1s orbital which has less energy than the 2s, and so requires much more energy to be removed.

An electron is transferred from the 2s orbital of lithium to form a Li ion. This results in the formation of a Li+ ion with a filled 1s and empty 2s orbital.
The complete electron configuration of lithium is 1s^2 2s^1. This means that lithium has 3 electrons, with 2 electrons in the 1s orbital and 1 electron in the 2s orbital.
The electron configuration for lithium is 1s^2 2s^1. This means that lithium has 3 electrons, with two in the 1s orbital and one in the 2s orbital.
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
In lithium, the orbital of highest relative energy is the 2s orbital. This is due to the fact that, in the electron configuration of lithium (1s^2 2s^1), the 2s orbital is farther from the nucleus compared to the 1s orbital, resulting in higher energy.
The valence electron of a lithium atom is in the 2s orbital. It is easily removed to form a lithium ion with a charge of +1 because lithium only has one valence electron, making it relatively easy to lose.
Each atom of lithium will have 3 electrons. Two electrons will fill the 1s orbital, and the third electron will occupy the 2s orbital, following the electron configuration of 1s^2 2s^1.

The element Lithium has a total of three electrons. The first two electrons would be placed in the 1s orbital. Then the third electron would be placed above the first two, in the 2s orbital. Because Lithium Ion has a +1 charge, one electron would be missing. So only the 1s orbital would be full.
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.
