What change was made to the Mendeleev’s early Periodic Table? (How is it currently organized? A.
They used atomic mass instead of atomic number to organize the elements.

B.
They included chemical properties such as bonding power.

C.
They included physical properties such as melting point and density.

D.
They used atomic number instead of atomic mass to organize the elements.

D

Explanation:

po promise meheehehehehe

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.
