An ion
Negative.
Since electrons are negatively charged, a nonmetal which gains an electron will also become negatively charged.
Sodium fluoride is an ionic compound. Sodium is a metal that donates an electron, and fluoride is a nonmetal that accepts the electron to form a stable ionic bond.
They become anions, with negative electrical charge.
Non-metals become negatively charged ions, also known as anions, after accepting an electron. This electron addition allows them to achieve a stable electron configuration similar to that of noble gases.
If an atom donates or accepts an electron it is considered an ion.
It is an ionic bond.
Bromine tends to gain one electron to achieve a stable electron configuration, making it an electron acceptor (accepts one electron).
A Lewis acid accepts an electron pair.
After chlorine accepts the electron from sodium, it becomes a chloride ion with a negative charge of -1.
Oxygen accepts the electrons at the end of the electron transport chain, ultimately forming water.
Sodium atoms will typically lose 1 electron when they react with a nonmetal to form an ionic compound. This electron loss enables sodium to achieve a stable electron configuration similar to that of a noble gas.
