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.
Li-Br is an ionic compound, not a molecule or atom. It is composed of lithium ions (Li⁺) and bromide ions (Br⁻) that are held together by ionic bonding.
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-)
An electron from the 2s orbital in a lithium atom is transferred to form a Li ion. This results in the lithium atom losing one electron, leading to the formation of a positively charged Li ion.
Lithium(Li)
The lithium atom lose an electron.
The formation of a lithium ion (Li+) from a lithium atom involves the loss of one electron. The equation can be written as: Li -> Li+ + e- where an electron is removed from the lithium atom to form a lithium ion.
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
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)
An electron is transferred from the 2s orbital to form Li+. This results in the removal of the outermost electron in the lithium atom, leading to the formation of a lithium ion.
