Ariana explains to her sister that there are some things you cannot see with your eyes, such as atoms. Which is a reason that some things cannot be seen with just your eyes? (A)Matter is made up of even smaller parts. (B)Matter that is tiny is too far away.(C)Matter moves faster as it gets smaller. (D)Matter that is small is too hot to see. This is (10 points) help

can you attach a picture of the lettuce? : )

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.  

a electronegativity decreases beacuse the size of nucleus is bigger.
