What do all types of steel have in common a: all alloys are made mostly of iron b: all are ionic compounds made from iron and nonmetals c: all are alloys that contain either iron, aluminum, or copper d: all are alloys made mostly of nonmetals

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.
