The principal quantum number for the outermost electrons in a Te atom in the ground state is .

The principal quantum number for the outermost electrons in a Te atom in the ground state is 5

Explanation:

In quantum chemistry, the region of maximum probability of where an electron is located is sometimes referred to as cloud or orbital.

The principal quantum number is used to express the state of an electron

The principal quantum number for the outermost electrons in a Te atom in the ground state is 5

The atomic number of Tellurium Te is Kr 4d¹⁰ 5s² 5p⁴

so quantum no is 5

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.
