What characteristic should an isotope used for dating have? O A. It should have a half-life much shorter than the age of the object
being dated.
B. It should have a half-life that is close to the age of the object being
dated.
O C. It should have a half-life that changes with time in the object being
dated.
O D. It should have a half-life much longer than the age of the object
being dated.

B. It should have a half-life that is close to the age of the object being

dated.

Explanation:

C. It should have a half-life that changes with time in the object being

dated.

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.
