When the valence (outer) shell has 5 or more electrons, excluding 8, including hydrogen, being more reactive when there are more electrons. This is because the atom wants to have 8 electrons in its outer shell (hydrogen wants 2), so those with 8 electrons don't want to react, while those with 7 REALLY want to react.
They are commonly referred to as anions and are traditionally the nonmetals. please send me a trust point if this helps =] sorry but that doesnt really help ={
An ion that has gained electrons would be a negative ion.
The type of ions that are formed by atoms gaining electrons are negatively charged ions.
These ions are called anions.
Common valences are 5 or 3.
An atom or molecule that gains an extra electron becomes a negatively charged ion. This can occur through various processes such as electron gain in chemical reactions or by gaining electrons from the environment.
Oxygen ionizes by gaining two electrons. It becomes a negatively charged ion with the formula O2-.
This is by gaining (-) or losing (+) electrons
This will produce a negative ion, called an anion. Non-metals such as chlorine form anions. See the link
Ion
electrons
An atom can become an ion by losing electrons. It can accomplish the same thing by gaining electrons.
oxidation. Gaining electrons is called reduction.
Gamma rays
Oxidation is an element or an ion getting a positive charge by removing valence electrons and Reduction is an element or an ion getting a negative charge by gaining free electrons. In chemical reactions reduction occurs by gaining the free electrons emitted by oxidation. Therefor oxidation and reduction proceed simultaneously.Oxidation is an element or an ion getting a positive charge by removing valence electrons and Reduction is an element or an ion getting a negative charge by gaining free electrons. In chemical reactions reduction occurs by gaining the free electrons emitted by oxidation. Therefor oxidation and reduction proceed simultaneously.
If atoms lose electrons they will have a positively charged ion called a cation. If they gain electrons, they will have a negatively charged ion called an anion.
An atom can become an ion by either gaining or losing electrons. If it gains electrons, it becomes an anion. If it loses electrons, it becomes a cation. An ion is merely an atom with a charge, either positive or negative.
well i think its an ion
It needs 2 electrons for this. Oxygen makes -2 ion by gaining 2 electrons. It is the most stable ion that oxygen makes.
Metals lose electrons and form cations.
