Aneutral atom possesses an number of 13 and an atomic mass of 27.three electrons are lost. from what region of the atom are they lost?

a. outside the atom

b. outside the nucleus

c. inside the nucleus

d. both inside and outside the nucleus

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.
