Web1 de fev. de 2024 · Sodium would become stable if it could lose an electron and attain the configuration of neon (2,8). Having picked up an electron the atom has become the negatively charged fluorine ion. This negative charge will electrically attract a positive ion, and repel a negative ion. Why is Na+ stable? Web27 de fev. de 2024 · By losing an electron to become the Na + cation, sodium’s underlying shell of 8 electrons becomes the ion’s outer shell with a stable octet. Chlorine attains a stable octet of 8 outer-shell electrons by gaining 1 electron per atom to produce Cl - ion. Figure 4.3. Formation of ionic sodium chloride from neutral Na and Cl atoms. Web2 de abr. de 2024 · Under some circumstances it is possible to prepare a solution which behaves anomalously and contains more solute than a saturated solution. Such a solution is said to be supersaturated. A good example of supersaturation is provided by Na 2 S 2 O 3, sodium thiosulfate, whose solubility at 25°C is 50 g Na 2 S 2 O 3 per 100 g H 2 O. in and out burgers christian
