What causes the movement of air as wind? (Select all correct answers) * The uneven heating of Earth's atmosphere
The differences in air pressure from one area to another
The duration of the solar year
The amount of direct sunlight an area receives

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.
