Uranium is a radioactive atom on the periodic table with 92 protons in its nucleusOne such isotope of uraniumUranium-235undergoes alpha decay by releasing an alpha particle and another radioactive isotope. The new isotope made during radioactive decay has an number of and a mass number of

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) the particles of the chair are strongly held together.
