The right answer will recieve a brainlest and ! what is the hypothesis of bath bombs ? (if, then ,because)

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.  

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.
