You have now seen how nuclear fission can cause chain reactions. What particle is largely responsible for a chain reaction? A) Proton
B) Neuton
C) Electron
D) Muon

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.

the atomic mass is the bottom number on the element.
