Lithium(Li) gains 1 electron to become stable.
The compound lithium chloride (LiCl) is formed.
Ionic bonding---with such different electronegativities it would be hard for lithium and fluorine to share electrons in a covalent bond. It is far more energetically favorable for the lithium atom to transfer an electron to fluorine to form Li+ and F- and then have those two hook up to form an ionic bond.

The charge of an electron is always −1.602176487(40)×10−19 Coulomb. If an electron is ejected from it's orbital the energy it absorbs is in the form of kinetic energy i.e. how fast it moves. If the electron goes back into an orbital it will only be allowed in an orbital that allows for it's energy. If an atom has an electron and that electron absorbs the energy from an incoming photon it may jump up to a higher orbital or it may be ejected. The ejected electron is the principle of the photo-electric effect.
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-
No. Lithium will lose an electron.
the valence electron of lithium that is easily removed is the 1s2 electron
Lithium(Li) gains 1 electron to become stable.
lithium donates an electron to bromine
The compound lithium chloride (LiCl) is formed.
Lithium loses one electron to become the cation Li+.
Lithium is in Group 1. It is an alkali metal. Neutral atoms of lithium have one electron in their outermost 2s energy level. Because of this, lithium atoms will lose their outermost electron to nonmetals to form ionic compounds, such as lithium chloride, or lithium oxide. When a lithium atom loses its outermost electron, it becomes a lithium cation with a charge of 1+. A cation is a positively charged ion.
Lithium gives one electron to another atom to form a stable mono-positive ion.
