The period number of any element is equal to the number of its energy levels true or false

The period number refers to the number of electron shells or primary energy levels an atom of each element has. Ex: Period 3 elements—Na, Mg, Al, Si, P, S, Cl, and Ar—have three primary electron energy levels.

true

Explanation:

sorry if wrong pa brainliest nalang :D

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.
