How many single covalent bonds must a phosphorus atom form to have a complete octet in its valence shell? how many single covalent bonds must a phosphorus atom form to have a complete octet in its valence shell? 3 1 4 0 2?

Option (a) is the correct answer.

Explanation:

Atomic number of phosphorous is 15 and its electronic configuration is .

As there are 3 valence electrons in a single phosphorous atom. Therefore, to attain stability it will readily lose three electrons and thus forms a charge.

For example, in there will be sharing of electrons between the phosphorous and chlorine atom.

Hence, a phosphorous atom can share its three valence electrons and thus forms three covalent bonds to have a complete octet in its valence shell.

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.
