he atomic number of fluorine is 9. How many electrons does an ion of fluorine have if it is represented by the symbol shown belo
2 answers:
The atomic number of fluorine is 9.
Atomic number is the number of protons present in the element. The number of electrons and protons is same in a neutral element.
The given ion of fluorine is . It represents a uninegative anion with a mass number of 19.
It is an anion with a charge of -1, this means that there is an additional electron in the ion. The number of electrons in this ion are 9 + 1 = 10 electrons
The correct answer will be C. 10 electrons

Answer: hydroxide ions
Explanation:
According to the Arrhenius concept, an acid is a substance that ionizes in the water to give hydronium ion or hydrogen ion and a bases is a substance that ionizes in the water to give hydroxide ion .
According to the Bronsted Lowry conjugate acid-base theory, an acid is defined as a substance which donates protons and a base is defined as a substance which accepts protons.
According to the Lewis concept, an acid is defined as a substance that accepts electron pairs and base is defined as a substance which donates electron pairs.
As KOH can give hydroxide ions on dissociation , it is considered as arrhenius base.
