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.
When an atom loses an electron, it becomes a positively charged ion.
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).
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.
The symbol for the cation formed when a potassium atom loses one electron is K+, and is named the potassium ion.
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.
Ion. Any atom that loses or gains an electron becomes an ion.
Ion. Any atom that loses or gains an electron becomes an ion.
When an atom loses an electron, it becomes a positively charged ion.
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).
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.
Yes, an ion is formed when an atom either loses or gains an electron, resulting in a net positive or negative charge, respectively. When an atom loses an electron, it becomes a positively charged ion, known as a cation.
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-).
