Electrons are not ions; an electron is an elementary particle with the electrically charge -1.
When potassium and fluorine bind, potassium will form a positive ion (K+) and fluorine will form a negative ion (F-). Potassium will lose an electron to become a cation with a +1 charge, while fluorine will gain an electron to become an anion with a -1 charge.
When a fluorine atom gains an electron, it forms a fluoride ion with a negative charge because it now has one more electron than protons. This gives it a full outer electron shell, making it more stable.
An electron is added in an atom to form a negative ion or anion. Because electron carry negative charge.
An ion with a positive charge is called a cation. Conversely, an ion with a negative charge is called an anion.
Fluorine is negative and will produce a negative ion.
Negative, when the ion gains an electron. When an ion loses an electron it becomes positive.
KClO4 has an ionic bond. In this compound, potassium (K) donates its electron to form a positive ion, while the perchlorate ion (ClO4) gains that electron to form a negative ion. The attraction between the positive and negative ions creates the ionic bond in KClO4.
When potassium achieves a noble gas electron configuration, it loses one electron to form the K+ ion. The K+ ion has a stable electron configuration similar to that of argon, with 18 electrons.
It will be a negative ion, or in other words, a anion.
When it gains an electron. It then becomes a negative ion.
it will become a negative ion due to the negative charge of electron
Adding one electron gives the chloride ion which has an octet (it achieves the same electron configuration as argon.
