Only one electron
Ionic bonds do not have valence electrons; rather, they form between atoms by electron transfer where one atom gives up electrons (cations) and the other gains electrons (anions). The resulting ions are held together by electrostatic forces, not by sharing electrons as in covalent bonds.
(7.6g LiBr)/(86.84g/mol) x (1molLi/1molBr) = .0875 mol Li or with sig figs, .088
Not atoms of LiBr; formula units is correct.1 mol = 6,022 140 857.10e23 (molecules, atoms, ions); this is the Avogadro number.6,022 140 857.10e23 x 1,25 = 7,52767607125.10e23 formula units of LiBr
Three electrons are transferred to form a bond between aluminum and sulfur because aluminum has 3 valence electrons while sulfur has 6 valence electrons. Aluminum donates its 3 electrons to sulfur, completing the octet for both atoms and forming an ionic bond.
In a binary covalent compound, there are no ions. Covalent compounds consist of nonmetal elements that share electrons rather than transfer them to form ions.
Only two electrons.
10 moles LiBr (6.022 X 1023/1 mole LiBr)= 6.022 X 1024 atoms of lithium bromide=========================
Two electrons are transferred in the ionic bond between Calcium and Oxygen. Calcium (Ca) loses two electrons to form Ca2+ ions, while Oxygen (O) gains two electrons to form O2- ions, resulting in the transfer of two electrons in total.

7,61 g LiBr contain 6,99 g Br.6,99 g Br is 0,087 moles.
The Krebs cycle does not directly pass electrons at a time. It generates electron carriers in the form of NADH and FADH2 by oxidizing acetyl-CoA to produce ATP and transfer electrons to the electron transport chain for further energy production.

In the non-ionic form, carbon has 6 electrons.
Aluminium lose 3 electrons and form the cation Al3+.
its a threesome
