Which ion is formed when an atom of fluorine (F) gains one electron?
2 answers:
Answer: Option (a) is the correct answer.
Explanation:
When an atom or element gains an electron then the atom acquires a negative charge whereas when an atom or element loses an electron then it acquires a positive charge.
for example, atomic number of fluorine is 9 and when it gains one electron then fluorine atom acquires a negative charge. Hence, neutral atom of fluorine changes into ion.
Thus, we can conclude that ion is formed when an atom of fluorine (F) gains one electron.
