Iodine gains electrons to form an anion (I-) through the process of reduction, as it has the ability to accept an electron to achieve a stable electron configuration.
Iron can both gain and lose electrons depending on the reaction it is involved in. In general, iron tends to lose electrons to form positively charged ions, such as Fe2+ or Fe3+, but it can also gain electrons to form negatively charged ions, such as Fe2-.
There would not be any. The electrons and protons would be equal so there would not be any that are leftover to use.
In iodine (I), the electron configuration is [Kr]5s²4d¹⁰5p⁵. This means that there are 10 electrons in the 4d orbital.
The ion would be Iodine (I). It has 53 protons and normally has 53 electrons, so if it gains an extra electron, it becomes a negatively charged ion with 54 electrons.
Silicon will tend to gain electrons in order to achieve a stable outer electron configuration, as it has 4 valence electrons and typically forms covalent bonds with other elements by sharing electrons.
They will loose electrons.
Metals lose electrons, nonmetals gain electrons.
Barium loses electrons to obtain a stable octet, like any other metal.
Iodine tends to gain one electron when it forms an ion.
It gains three, loses five, or shares pairs of electrons
No, iodine typically gains electrons to form the iodide ion in a chemical change. This is due to iodine's tendency to exhibit an oxidation state of -1.
ions
They need to gain them.
Metals loss electrons and nonmetals gain electrons.
Iodine typically gains an electron to form a -1 ion.
Metals will LOSE electrons to become stable.
Atom loose or gain electron to make its octet complete. It is done to achieve inert state.
