it gains or acquires a charge either positive or negative so when it gains energy, it aquires a negative charge then when it loses energy, it aquires a positive charge
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).
Ion. Any atom that loses or gains an electron becomes an ion.
Negative, when the ion gains an electron. When an ion loses an electron it becomes positive.
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 positive ion can become a neutral atom by gaining electrons. When a positive ion gains one or more electrons, it becomes neutral because the negative charge of the electron(s) cancels out the positive charge of the ion.
Potassium loses one electron.
An Ion. More specifically if it gains an electron it becomes an anion and it it loses an electron it becones an cation (pronounced Kat-ion)
This is called a redox reaction. An atom that loses an electron is oxidized and an atom that gains an electron is reduced.
Ion. Any atom that loses or gains an electron becomes an ion.
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-).
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).
no
gains or loses an electron.
Ion. Any atom that loses or gains an electron becomes an ion.
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.
