Which locations are likely to have subatomic particles that are constantly in motion: A) 1 and 2
B) 2 and 3
C) 1 and 3
D) 2 and 4

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.  

it is stable as it is in group 0 which have full outer shells of electrons

gasoline is a mixture. it contains several different kinds of compounds that can be present in a variety of ratios.
