When an atom loses an electron, it becomes a positively charged ion, called a cation.
In chemist Michael Faraday's nomenclature, cations were named because they were attracted to the cathode in a galvanic device and anions were named due to their attraction to the anode.
Ion. Any atom that loses or gains an electron becomes an ion.
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.
a neutral atom :)
oxygen atom
If an atom gains an electron, it becomes an anion, which is negative. Anions are larger than the original atom because of the added electrons. N + electron(-) --> N(-) If an atom loses an electron, it becomes a cation and positively charged. Cations are smaller than the original atom because of the lost electrons. N(2+) = cation
This is called a redox reaction. An atom that loses an electron is oxidized and an atom that gains an electron is reduced.
an isotope
If an atom loses an electron it becomes a negative ion, called an anion.
The atom that gains electron becomes an anion. The atom that loses electron becomes a cation.
Ion. Any atom that loses or gains an electron becomes an ion.
Ion. Any atom that loses or gains an electron becomes an ion.
It loses a negative charge and then becomes a positive ion
When an atom loses an electron it becomes a positively charged ion.
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.
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-).
