Question

Why does fluorine give only one oxide but chlorine gives a series of oxidea?

Answer 1

Fluorine is the member of halogen family. It is placed in 17th group of the periodic table .

It contains seven electrons in the valence shell,hence it requires one electron to complete it’s otet.Thus by gaining one electron it shows -1 oxidation state.

Valence shell is second shell in case of fluorine,which do not have vaccant d-orbital. So it can not show variable valency.

Due to exceptionally smaller atomic size and presence of seven electrons in valence shell,it has high electronegativity values.

Answer 2

Answer:

Fluorine due to high electronegativity , shoes only one oxidation state equal to -1 so it forms only one oxide namely F2O. On the other hand, chlorine shows many oxidation states like +1,+4,+6,+7 so it forms series of oxides
