An atom that has gained an electron has a negative charge and is called an 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 gains an electron, it becomes negatively charged and forms an anion. This process is known as reduction, and it can change the chemical properties of the atom by affecting its reactivity and ability to form bonds.
Ion. Any atom that loses or gains an electron becomes an ion.
positively
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.
an atom that gains an electron becomes a negative ion, called an anion.
it forms an ionic bond with the atom it has received an electron from.
This is called a redox reaction. An atom that loses an electron is oxidized and an atom that gains an electron is reduced.
An Electron
an anion
An atom that gains three electrons will become an ion with a 3- 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.
When a chlorine atom gains one electron, it forms a chloride ion with a single negative charge.
When an atom gains an electron, it becomes negatively charged and forms an anion. This process is known as reduction, and it can change the chemical properties of the atom by affecting its reactivity and ability to form bonds.
When an atom gains an electron the no of negatively charged particles increases inside the atom and the atom gets negatively charged.
The energy change that occurs when an atom gains electrons is called the
