Metallic character goes on decreasing while going from left to right in a period.

The sun is seen above the horizon, a little before sunrise.

please answer the question urgently required!!

Metallic character goes on decreasing while going from left to right in a period because the tendency of atoms of the elements to lose electrons(or gain electrons) changes in a period. As we move from left to right in a period, the nuclear charge increases due to gradual increase in the number of protons.

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.  

the right answer is c i just did the question.
