If an atom loses or gains electrons, it will become a positively or negatively charged particle, called an ion. The loss of one or more electrons results in more protons than electrons and an overall positively charged ion, called a cation.
When an atom gains an electron, the resulting particle is called. an anion. The charges on electrons and neutrons cancel each other to give neutral atoms.
The atom that has lost an electron becomes a positively charged ion (called a cation), while the atom that picks up the extra electron becomes a negatively charged ion (called an anion).
Ions are formed by the addition of electrons to, or the removal of electrons from, neutral atoms or molecules or other ions; by combination of ions with other particles; or by rupture of a covalent bond between two atoms in such a way that both of the electrons of the bond are left in association with one of the ...
Reduction is gain of electrons, loss of oxygen or gain or hydrogen. Rusting is an example of oxidation.
When an atom loses an electron, the resulting particle is called: A cation.
When an atom loses an electron, it loses a negative charge and becomes a positive ion.
Atoms and chemical species lose or gain electrons when they react in order to gain stability. Thus, typically, metals (with nearly empty outer shells) lose electrons to non-metals, thereby forming positive ions. The number of electrons depends on their position on the Periodic table (in simple terms).
Cations are positively charged ions formed when neutral atoms lose electrons; anions are negatively charged ions formed when neutral atoms gain electrons.
Ionic bonds form only between metals and nonmetals. That's because metals “want” to give up electrons, and nonmetals “want” to gain electrons. It takes energy to remove valence electrons from an atom and form a positive ion.
