Want this question answered?
The lithium atom lose an electron.
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.
The number of protons will always be 3 in each Li atom, and either 3 or 4 neutrons, depending on the Li atom's isotope. 6Li has 3 protons, while 7Li has 4. All other isotopes of Lithium are unstable.
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 is small atom and thus have comparatively compactly arranged electrons.. It seizes the Cl atom to take away its electron...thus it have covalent bond rather than ionic.. K is bigger in size..have weak nuclear attraction...screening and shielding effect is more in K,..therefore can form gud ionic bonds.... ok dear..
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-)
Lithium(Li)
The lithium atom lose an electron.
the answer will be Li2+ ion because it has one electron as in the case of hydrogen atom.
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

a metallic bond
From the second s orbital: Li(1s2, 2s1) --> Li+(1s2, 2s0) + 1e-
