This is called a redox reaction. An atom that loses an electron is oxidized and an atom that gains an electron is reduced.
The energy change that occurs when an atom gains electrons is called the
It become an ion, positively charged when it loses an electron (called a cation, e.g. Na+) or negatively charged when it gains an electron (called a anion, e.g. Cl-).
A cation is a positively charged particle formed by the loss of one or more electrons from an atom.
Gains: anion (-) Loses: cation (+)
An ion is formed when an atom gains or loses an electrons or electrons. If it gains an electron, it becomes an anion, and if it loses an electron it becomes a cation.
an atom that gains an electron becomes a negative ion, called an anion.
This is called a redox reaction. An atom that loses an electron is oxidized and an atom that gains an electron is reduced.
an anion
An atom that has gained an electron has a negative charge and is called an anion.
The energy change that occurs when an atom gains electrons is called the
Ion. Any atom that loses or gains an electron becomes an ion.
Ion. Any atom that loses or gains an electron becomes an ion.
if an atom gains an eletron it is more negative and ic called a anion
An atom forms an ion when it gains or loses an electron. If an atom gains an electron, it becomes a negatively charged ion (anion). If an atom loses an electron, it becomes a positively charged ion (cation).
When an atom looses an electron is called "a cation, when gains is called an "anion".
A neutral atom that subsequently gains or loses one [or more] electrons is called an ion. If it gains an electron [or electrons] it will have a negative charge. If it loses an electron [or electrons] it will have a positive charge.
