THe lithoium atom has IONISED ( lost) an electron, to become the lithium ION.
I'm pretty sure there are 3 atoms because in Li2o, there are 2 atoms in lithium and 1 atom in oxygen.
The Li ion is different from the atom because it has positive charge. (Lithium is group 1 element and these lose 1 electron to form for example :Li+ , Na+ etc)
Li is atom number three, not only 'was' but it still is and ever will be.
It is a molecule, atoms are only of one type and though both have partial charges due to the way the bond is formed they are not ions in this state.
Na have higher shielding effect than Li *According to my chemistry book
The reduction in the force of attraction between the nucleus and the valance electrons by the electrons present in the inner subshells is called shielding effect.As you move from top to bottom in a group number of electronic shells increase so the number of electrons in the inner shells also increases. As a result shielding effct increases.Therefore Na will have higher shielding effect than Li as it comes after Li in the group.
Li+ and Cl-
Li atom donates one electron to a Cl atom when Li+Cl- is to be formed as ionic compound (salt):Li --> e- + Li+Cl + e- --> Cl--------------- +Li + Cl --> LiCl (or Li+Cl-)
From the second s orbital: Li(1s2, 2s1) --> Li+(1s2, 2s0) + 1e-
Lithium(Li)
Correct answer:LiLiYour response:Li+Correct answer:Your response:Correct answer:Li+Li^+^Your response:Li++Correct answer:e-e^-^Your response:e+
Li+ means that the atom lost an electron. And this means it has now has a complete outershell, thus being more stable than the Lithium atom with 1 valence electron

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.
