Question

question 2
which is the most reactive non - metal?
chlorine
fluorine
helium
radon

Explanation:

• Chlorine is a reactive non - metal but less reactive than fluorine.
• Fluorine has a very high electronegativity and a strong tendency to gain an electron (due to its small atomic size and high nuclear charge relative to its electron shell configuration), making it extremely reactive.
• Helium is a noble gas with a full valence shell, so it is inert (non - reactive).
• Radon is also a noble gas (although it is radioactive), and noble gases generally have very low reactivity because of their stable electron configurations.

Answer:

Fluorine
