On the other hand, iodine is located in group 17 (main group 7), which means it has 7 valence electrons. Does Group 5 gain or lose electrons? Ions. In positive IONS. Consequently, does iodine lose or gain an electron? When these atoms gain electrons, they acquire a negative charge because they now possess more electrons than protons. When an atom loses electrons it becomes a cation. Reduction is gain of electrons. An example of this is the reaction between the metal, sodium, and the non-metal, chlorine. Negatively charged ions are called anions. Essentially, gaining and losing electrons (i.e., participating in chemical reactions) is necessary for life as it exists on Earth today. A positive ion is called a cation (pronounced: CAT-eye-on). All other shells are complete when they are the outer shell if they contain 8 electrons.

Found inside – Page 112It contains the proteins needed for the electron transfer chain and also ATP ... can be oxidised by losing electrons, losing hydrogen or gaining oxygen. For example, fluorine has seven valence electrons, so it is most likely to gain one electron to form an ion with a 1- charge. For sodium metal to become sodium ions in sodium oxide, it must give its valence electron to oxygen. When forming ions, elements typically gain or lose the minimum number of electrons necessary to achieve a full octet. Metal atoms frequently lose all of their valence electrons, leaving them with an octet from the lowest primary energy level. A beryllium ion can become a beryllium atom by gaining 2 electrons. Ions. Thus, typically, metals (with nearly empty outer shells) lose electrons to non-metals, thereby forming positive ions. If it loses an electron it becomes a positive ion (see page 10 for more on ions). ions of different elements can combine by forming ionic bonds .

The charge on an atom, and therefore the type of ion it becomes depends on the number of electrons lost or gained. In other words, their nuclei are identical. ; Negative Ion - Occurs when an atom gains an electron (negative charge) it will have more electrons than protons. This is because without this cookie we cannot remember your cookie settings. Metals tend to lose electrons and non-metals tend to gain electrons, so in reactions involving these two groups, there is electron transfer from the metal to the non-metal. Meanwhile, the oxygen atoms in oxygen molecules receive the electrons to become oxide ions. The sodium atom wants to lose an electron and the chlorine atom wants to gain an electron.

All oxidations meet criteria 1 and 2, and many meet criterion 3, but this is not always easy to demonstrate. For example, a magnesium atom can turn into a magnesium ion and a magnesium ion can turn into a magnesium atom or a different kind of magnesium ion, but a magnesium atom or ion could never turn into a sodium atom or ion by gaining or losing electrons. Alternatively, an oxidation can be described as a transformation of an organic substrate that can be rationally dissected into steps or primitive changes. The type of ion that an atom becomes depends on whether it gains or loses electrons. A Cu2+ ion can become a Cu+ ion by gaining an electron.
