It would be -1 because gaining an electron will create a negative charge. F has a high electron affinity and therefore becomes an F- ion quite readily.
A fluorine ion with a charge of 1 indicates that it has gained an extra electron, making it a fluoride ion. So, a fluoride ion would have 10 electrons (9 from the protons and 1 extra electron).
The symbol for fluorine as an ion is F-.
They are called ions because they have an electric charge. The sodium gives up its (valence) electron so it gains a positive electrical charge. The chlorine gains this extra electron so it gains a negative electrical charge. IONS always refer to particles WITH AN ELECTRICAL CHARGE.
The chloride ion in salt has a charge of -1. It is derived from an atom of chlorine that has gained one electron to achieve a full outer electron shell, resulting in a negative charge.
Hydroxide (OH-) has a negative charge because it has gained an extra electron, giving it a net negative charge of -1. This extra electron is acquired when a hydrogen ion (H+) is donated to the hydroxide ion as part of a chemical reaction.
Ion
Electron(s).
Gained or lost electron(s).
A fluorine ion with a charge of 1 indicates that it has gained an extra electron, making it a fluoride ion. So, a fluoride ion would have 10 electrons (9 from the protons and 1 extra electron).
A fluorine ion with atomic number 9 and 10 electrons has a charge of -1 because it has one extra electron as compared to the number of protons (10-9 = 1). Its symbol is F-.
I believe the answer your looking for in an Ion.An ion is an atom or molecule in which the total number of electrons is not equal to the total number of protons, giving it a net positive or negative electrical charge.
Fluorine gains one electron to achieve a stable electron configuration of a full outer shell.
When fluorine reacts with a metal, it gains an electron to form the fluoride ion (F-). This process is called reduction, as the fluorine atom is gaining electrons.
It accepts one electron.
Fluorine has 7 valence shell electrons. If it has a formal charge of (-1) that means that it has 8 non bonding electrons. Its atomic number is 9 therefore the fluorine anion (F-1) has 8 electrons and 9 protons.
The symbol for fluorine as an ion is F-.
The element that has 9 protons is fluorine. Its atomic number is 9, indicating that the element has 9 protons in the nuclei of its atoms. If there are 10 electrons, then the fluorine atom has gained an electron and is now a negatively charged anion with a charge of 1-.
